The local sheriff is concerned about speeding at a particular intersection. He selects a random sample of 30 hours over the course of a month and records the average speed of all vehicles that travel through that intersection during each hour. The overall average speed was found to be 36.2 miles per hour. The sheriff would like to conduct a hypothesis test to determine if the overall average speed is significantly higher than 35 miles per hour. Select all of the correct null and alternative hypotheses. Select one or more: Ho: μ = 36.2 Ho: μ = 35 Ho: x̄ = 36.2 Ha: μ > 35 Ha: μ < 35 Ha: μ ≠ 35

Step 1
In this case, the null hypothesis would be: \[H_0: \mu = 35\] where \(\mu\) represents the population average speed at the intersection. ** Show more…

A commonly cited standard for one-way length (duration) of school bus rides for elementary school children is 30 minutes. A local government office in a rural area randomly samples 100 elementary school children in their district and find an average one-way commute time of 38 minutes with a standard deviation of 8 minutes. Which of the following is the correct set of hypotheses for testing if the average commute time of elementary school students in this district is different than the commonly cited standard of 30 minutes? HA: μ = 30; H0: x ≠ 30 H0: μ = 30; HA: μ > 30 H0: μ = 30; HA: x = 38 H0: x = 38; HA: μ = 30 H0: μ = 30; HA: μ ≠ 30

A commonly cited work week hours for an employee is 36 hours. A company samples 100 employees and find an average work week hours of 47 hours with a standard deviation of 11 hours. Which of the following is the correct set of hypotheses for testing if the average work week hours of an employee of this company is different than the commonly cited standard of 36 hours? H0: x = 47; HA: μ = 36 H0: μ = 36; HA: μ ≠ 36 HA: μ = 36; H0: x ≠ 36 H0: μ = 36; HA: μ > 36 H0: μ = 36; HA: x = 47

Testing Claims Using P-Values $(a)$ identify the claim and state $H_{0}$ and $H_{a}$, (b) use technology to find the P-value, (c) decide whether to reject or fail to reject the null hypothesis, and (d) interpret the decision in the context of the original claim. Assume the population is normally distributed. Oil Changes A repair shop believes that people travel more than 3500 miles between oil changes. A random sample of 8 cars getting an oil change has a mean distance of 3375 miles since having an oil change with a standard deviation of 225 miles. At $\alpha=0.05,$ do you have enough evidence to support the shop's claim?
