Q1. Let x be a random variable that represents red blood cell count (RBC) in millions of cells per cubic millimeter of whole blood. Then has a distribution that is approximately normal. For the population of healthy female adults, suppose the mean of the distribution is about 4.72. Suppose that a female patient has taken 6 laboratory blood tests over the past several months and that the RBC count data sent to the patient's doctor are as follows.4.9, 4, 4.6, 4.3, 4.5, 4.3Do the given data indicate that the population mean RBC count for this patient is lower than 4.72? Use a= 0.01 .D) Accurate to 3 decimal places, find the t* value of the sample.F) Aucurate to 4 decimal places, what's the p-value of the sample?Q2. Let x be a random variable that represents hemoglobin count (HC) in grams per 100 milliliters of whole blood. Then has a distribution that is approximately normal, with population mean of about 13 for healthy adult women. Suppose that a female patient has taken 10 laboratory blood tests during the past year. The HC data sent to the patient's doctor are as follows.16, 20, 18, 18, 15, 11, 14, 18, 17, 14Do the given data indicate that the population mean HC for this patient is higher than 13? Use a= 0.05. D) Accurate to 3 decimal places, find the t* value of the sample.

Jess is a cheerleader for her high school. When she practices her routine at home alone, her arousal is low and she often gets distracted and makes mistakes. When she performs in front of her whole high school, she sometimes gets too nervous and aroused and also makes mistakes. Her best performances are typically at small competitions when her arousal level is moderate. The variations in Jess's performance can be best explained by the James-Lange theory. Yerkes-Dodson law. Drive Reduction theory. Cannon-Bard theory.

Do a hypothesis test on the claim that the proportion of all females who always wear a seat belt equals the proportion of males who do the same if 90 out of 150 females say they always weat a seat belt while 75 out of 150 males say they always wear a seat belt. Use $\alpha = 0.05$ Select the correct conclusions. $\square$ Since test statistics $\in$ critical region, reject $H_0$ $\square$ Since test statistics $\in$ critical region, do not reject $H_0$ $\square$ Since test statistics $\notin$ critical region, reject $H_0$ $\square$ Since test statistics $\notin$ critical region, do not reject $H_0$ $\square$ Since p-value $> \alpha$, reject $H_0$ $\square$ Since p-value $> \alpha$, do not reject $H_0$ $\square$ Since p-value $< \alpha$, reject $H_0$ $\square$ Since p-value $< \alpha$, do not reject $H_0$ $\square$ There is sufficient evidence to reject the claim. $\square$ There is no sufficient evidence to reject the claim. $\square$ The data support the claim. $\square$ The data do not support the claim.

Which of the following is a better Lewis structure for the NaO molecule? Why is the structure you chose better than the other structure? N=N=O: : N= -N O The right structure is better because it contains the correct number of valence electrons. The right structure is better because it places the negative charge on the more electronegative atom. O The left structure is better because it follows the octet rule. O The left structure is better because it minimizes formal charge. ) The left structure is better because it places the negative charge on the more electronegative atom.

A very long Teflon rod (cylindrical in shape) is held in water. The radius of the rod is 20 mm. An external electrostatic field exists in the water and is \(\vec{E} = 3\hat{x} + 5\hat{y}\) (volts/metre). If the rod is aligned with the z axis, come up with an expression for the surface charge density on the surface of the rod. [$\epsilon_{Teflon} = 2.1\epsilon_0$ and $\epsilon_{water} = 81\epsilon_0$]
