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%? O Yes, because the p-value 0.15 No, because the p-value = 0.15 O No, because the p-value = 0.10 Yes, because the p-value 0.10

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%?If, in a one-tail hypothesis test where H0 is only rejected in the upper tail, the p-value=0.2047 and ZSTAT=+0.82, what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision?
- According to the National Highway and Traffic Safety Administration, the proportion of fatal traffic accidents in the United States in which the driver had a positive blood alcohol concentration (BAC) is .36. Suppose a random sample of 105 traffic fatalities in the state of Hawaii results in 51 that involved a positive BAC. D) Check whether the conditions for hypothesis testing using the P-value approach are meet.A health provider saw that 48% of their members received their flu shot in recent years. The health care provider tried a new advertising strategy the following year, and they took a sample of members to test if the proportion who received their flu shot had changed. Determine the null and alternative hypothesisA 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…
- A sample poll of 500 voters from Michigan and 300 voters from Wisconsin showed that 51% and 49% is in favor of Donald Trump, respectively. At a significance level of 0.05, and using two-tailed test: a.) What should be the good hypotheses? b.) What is the t-value/z-value? c.) Is there is a difference between the two states?According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumer complaints ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a lower proportion of identity theft than 23%? Test at the 5% level. viii) Comparing p-value and α value, which is the correct decision to make for this hypothesis test? A. Reject H B. Fail to reject Ho C. Accept Ho D. Accept HA Enter letter corresponding to correct answer. (ix) Select the statement that most correctly interprets the result of this test: A. The result is statistically significant at .05 level of significance. Evidence supports the claim that the proportion of complaints due to identity theft in Alaska is less than 23%. B. The result is statistically significant at .05 level of significance. There is not…A ski lift manager is interested in the average daily number of ski lift users. In previous years, fewer than 945 people, on average, have used the ski lift daily over the winter season. The manager suspects this average has increased in recent years.

Reject the null hypothesis and accept the alternate hypothesisIf, in a (two-tail) hypothesis test, the p-value is 0.1064, what is your statistical decision if you test the null hypothesis at the 0.06 level of significance? Choose the correct answer below? A. Since the p-value is greater than α, do not reject H0. B. Since the p-value is less than α, reject H0. C. Since the p-value is greater than α, reject H0. D. Since the p-value is less than α, do not rejectIf, in a (two-tail) hypothesis test, the p-value is 0.0921, what is your statistical decision if you test the null hypothesis at the 0.06 level of significance?
