The pizza chain aims to deliver within 20 minutes on average. What would be the null and alternative hypotheses if the pizza chain wishes to conduct a hypothesis test to assess whether they have exceeded the target delivery time?a.H0 µ = 20 minutes, H1: µ ≠ 20minutesb.H0: µ = 20 minutes, H1: µ < 20 minutesc.H0: µ = 20 minutes, H1: µ > 20 minutesd.H0: µ < 20 minutes, H1: µ > 20 minutes

At one school, the average amount of time that tenth-graders spend watching television each week is 18.4 hours. The principal introduces a campaign to encourage the students to watch less television. One year later, the principal wants to perform a hypothesis test to determine whether the average amount of time spent watching television per week has decreased. Formulate the null and alternative hypotheses for the study described.Question 17Answera.H0: µ = 18.4 ; H1 µ ≠18.4b.H0: µ < 18.4 ; H1 µ > 18.4c.H0: µ = 18.4 ; H1 µ <18.4d.H0: µ > 18.4 ; H1 µ <18.4

Based on your results, which of the following is TRUE? Use the significance level of 0.05 for your analysis.a.There is enough evidence to suggest that the average delivery time is longer than 20 minutes.b.There is enough evidence to suggest that the average delivery time is less than 20 minutes.c.There is not enough evidence to suggest that the average delivery time is longer than 20 minutes.d.There is not enough evidence to suggest that the average delivery time is less than 20 minutes.

Hypothesis Testing

Formulating the HypothesesIt is believed that the average commute time for an employee to and from their office in Hyderabad is at least 35 minutes. Now, suppose you want to test this claim.What will be the null and alternative hypotheses in this case if the average commute time is represented by μ?Ho: μ ≤ 35 minutes; Ha: μ > 35 minutesHo: μ > 35 minutes; Ha: μ ≤ 35 minutesHo: μ ≥ 35 minutes; Ha: μ < 35 minutesHo: μ < 35 minutes; Ha: μ ≥ 35 minutes

Which of the following would be an appropriate null hypothesis?
