Genetics Ribosomal 5S RNA can be represented as a sequence of 120 nucleotides. Each nucleotide can be represented by one of four characters: A (adenine), G (guanine), C (cytosine), or U (uracil). The characters occur with different probabilities for each position. We wish to test whether a new sequence is the same as ribosomal 5S RNA. For this purpose, we replicate the new sequence 100 times and find there are 68 A's in the 20th position. You can use the Distribution Calculators page in SALT to find critical values and/or p-values to answer parts of this question. Please note that the Inferential Statistics page does not use the continuity-corrected version of the test statistic. (a) If the probability of an A in the 20th position in ribosomal 5S RNA is 0.79, then test the hypothesis that the new sequence is the same as ribosomal 5S RNA using the critical-value method. (Use $\alpha = 0.05$.) State the null and alternative hypotheses. (Enter != for $\neq$ as needed.) $H_0$: $H_1$: Find the test statistic. (Round your answer to two decimal places.) Find the critical value. (Round your answer to two decimal places.) State your conclusion. O Reject $H_0$. There is insufficient evidence to conclude that the new sequence is different from ribosomal 5S RNA. O Fail to reject $H_0$. There is insufficient evidence to conclude that the new sequence is different from ribosomal 5S RNA. O Reject $H_0$. There is sufficient evidence to conclude that the new sequence is different from ribosomal 5S RNA. O Fail to reject $H_0$. There is sufficient evidence to conclude that the new sequence is different from ribosomal 5S RNA. (b) Use technology to report a p-value corresponding to your results in (a).

A single point charge of unknown magnitude is isolated in a region of space. The electric field magnitude is measured to be 372 N/C and the voltage is measured to be 84.1 V at one location near the charge. a) Calculate the distance between the charge and the location where the measurements were made (in cm).b) Calculate the charge (in nC).

Daniel Shay, like most other farmers, faced high tax bills after the war. A demand for and a supply of money drove interest rates . As a result, Shay and other farmers grew crops that led to a(n) of supply of food which food prices. This ultimately led to Shay's rebellion which convinced many folks in 1787, that the central government was too .

We found that the time after the mass passes through the equilibrium point at which the mass attains its extreme displacement from the equilibrium position is $\frac{3}{4}$ seconds. Lastly, we must find the position of the mass at the instant the mass attains its extreme displacement from the equilibrium, which is $x(\frac{3}{4})$. We note that the result is measured in feet. $x(t) = -e^{-4t} + 2te^{-4t}$ $x(\frac{3}{4}) = -e^{-4(3/4)} + 2(\frac{3}{4})e^{-4(3/4)}$ = .023 ft

George has a personal auto policy that provides the following coverages: liability coverage $150,(000)/($)300,(000)/($)50,000,$5,000 medical payments coverage, $25,(000)/($)50,000 uninsured motorists coverage, $500 deductible for a collision loss, and a $100 deductible for an other-than-collision loss. With respect to each of the following situations, indicate whether or not the losses are covered, and if possible, the dollar amounts that would be paid by the insurance company. Assume that each situation is a separate event. Clearly identify what section of the policy is controlling and why the event is either covered or not covered. (15 points) (a) George's son, age 16 , is driving a family car and kills a pedestrian in a drag racing contest on an isolated stretch of highway. The heirs of the deceased pedestrian sue for $175,000. The family car is destroyed. It has an actual cash value of $12,000 and a replacement cost of $29,000. (b) George's daughter, Cindy, attends boarding school in another state and does not have a driver's license. Cindy is 15 years old. Cindy tells her boyfriend she is 16 years old and while driving the boyfriend's car, Cindy hits and negligently injures another motorist. Cindy is sued for $60,000 for bodily injury and $20,000 for property damage. The boyfriend's car will cost $4,000 to repair but has an actual cash value of only $2,000.

(c) George is driving home from work and hits a deer. The damage to the car is $2,800. The lights won't work, and one tire is flat, but George decides to drive home anyway. He fails to see a car parked on the street next to his house and crashes into it. Damage to the other car is $8,500. By driving on the flat tire, George increases the damage to his own car from $2,800 to $3,300. (d) George owns a vintage 1970 car that he is fixing up in his garage. The car is not listed on George's auto insurance policy and George carries no insurance on this vehicle. George's daughter takes the vintage car for a ride while George is out shopping in the family's minivan. On his way home, George's minivan is hit by his vintage car driven by his daughter.

The daughter also suffers minor injuries. Her medical bills total $800. (e) George's son Frank borrows George's car to take his girlfriend to the High School Prom. Frank's girlfriend has a driver's license but no one in her family owns a car, and therefore she has no auto insurance of her own. Frank lets his girlfiend drive George's car, and she hits another car. Damage to the other car is $5,000 and the driver is injured, with $15,000 in medical bills.

Question 1 1 pts A researcher measured lead levels in children in a Michigan county both before and after the water source for that county was switched to Flint, Michigan. The following are lead levels (µg/dL) from children living in one - small neighborhood that was sampled: Pre-switch 0 1 0 7 Post switch 6 9 8 10 At the \alpha=0.05 level, test for a change in lead levels after switching water source. What is your interpretation? Lead levels among children were not significantly different after switching the water source. Lead levels among children were significantly higher after switching the water source. Lead levels among children were significantly lower after switching the water source. I haven't finished the exercise in time.
