A study is conducted to determine if bus ridership in a large city is higher during the afternoon rush hours than morning rush hours. The transit authority randomly selects nine buses and on a given day counts the number of riders at 7:45 AM and 4:45 PM. The results are shown below. Conduct an appropriate hypothesis test using 0.05 level of significance. Morning 43 43 37 25 47 42 48 55 52 Afternoon 41 49 44 32 46 55 53 52 50 Determine which of the following formulations of the hypotheses is most appropriate and enter the corresponding number in the answer text box. Note: Index “a” refers to the population of afternoon bus riders and index “m” refers to the population of morning bus riders. For example if you think formulation number 3 is the most appropriate formulation for this problem then enter “3” in the answer text box and re-enter to confirm.

A fast-food restaurant claims that a small order of french fries contains 120 calories. A nutritionist is concerned that the true average calorie count is higher than that. The nutritionist randomly selects 35 small orders of french fries and determines their calories. The resulting sample mean is 155.6 calories, and the pp-value for the hypothesis test is 0.00093. Which of the following is a correct interpretation of the p-value? A)If the population mean is 120 calories, the p -value of 0.00093 is the probability of observing a sample mean of 155.6 calories or more. B) If the population mean is 120 calories, the p -value of 0.00093 is the probability of observing a sample mean of 155.6 calories or less. C)If the population mean is 120 calories, the p -value of 0.00093 is the probability of observing a sample mean of 155.6 calories or more, or a sample mean of 84.4 calories or less. .D)If the population mean is 155.6 calories, the p -value of 0.00093…
1. A Gallup poll on energy use randomly selected 520 adults and asked if they favoured“increasing the use of nuclear power as a major source of energy”. The poll reported that 224 adults said “Yes”. Does this poll give good evidence that more than 39% of all adults are in favour of the increased use of nuclear power? a) Write down the null and alternative hypotheses. b) Check the necessary assumptions for carrying out the hypothesis testing. c) Compute the observed test statistic. d) Find the corresponding P-value. e) Based on the P-value in (d) and α = 0.03, what are the decision and final conclusion?
Are the requirements met to test a hypothesis for the following two population proportions? If not, state which requirement is not met, and show whyit fails. In a random sample of 100car owners, 85% said they were happy with the fuel economy of their car. In a random sample of 80truck owners, 4% said they were happy with the fuel economy of their truck.
1) Use the pulse rates in beats per minute (bpm) of a random sample of adult females listed in the data set available below to test the claim that the mean is less than 80 bpm. Use a 0.01 significance level. Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?

Conduct the appropriate hypothesis test and compute the p-value. Sunshine Air has determined that their no-show rate for passengers booked on a flight is 6%. The Airline has recently increased the cost of its travel insurance and and suspects the no-show rate for passengers will decrease. A random sample of 380 reservations resulted in 18 no-shows. At the 0.10 significance level, is there strong enough sample evidence to suggest that the no-show rate in less than 6%?
Assuming that all the assumptions of statistical hypothesis testing are met, based on the z-score of 1.96 and the sample size of 200, the appropriate conclusion for this test would be? a) P-value is under .05, we would reject the null hypothesis b) P-value is over .05, we would failed to reject the null hypothesis c) P-value is under .05, we would fail to reject the null hypothesis d) P-value is over .05, we would reject the null hypothesis
