In a certain city, the population mean commute time to work was reported as 30 minutes. The director of human resources for a certain company in the city claimed the mean commute time the company's employees was greater than 30 minutes. The director surveyed 35 randomly selected employees and found that their mean commute time was 31.4 minutes. With all condition for inference met, a hypothesis test conducted at the significance level a = 0.05 resulted in a p-value of 0.381. Which of the following is an appropriate conclusion? The director has convincing statistical evidence to conclude that the population mean commute time is greater than 30 minutes. The director has convincing statistical evidence to conclude that the population mean commute time is less than 30 minutes. The director has convincing statistical evidence to conclude that the population mean commute time is 31.4 minutes. D The director does not have convincing statistical evidence to conclude that the population mean commute time is greater than 30 minutes. The director does not have convincing statistical evidence to conclude that the population mean commute time is less than 30 minutes.

The average student loan debt is reported to be $25,235. A student belives that the student loan debt is higher in her area. She takes a random sample of 100 college students in her area and determines the mean to be $27,524 and the standard devition to be $6000. Is there sufficient evidence to support the student' claim at a 5% significance level?a) Determine the null and alternative hypotheses.H0H0: μ=μ=HaHa: μμSelect an answer > not = < (Put in the correct symbol and value)b) Determine the test statistic.

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1421 referee calls, with the result that 418 of the calls were overturned. Women challenged 778 referee calls, and 228 of the calls were overturned. Use a 0.01 significance level to test the claim that men and women have equal success in challenging calls.

According to an NDP Group report, the mean number of meals prepared and eaten at home is 700 per year. Suppose that a random sample of 36 households showed a sample mean number of meals prepared and eaten at home was 690. Assume σ = 40. Test whether the population mean number of such meals is less than 700 using a significance level of 0.01. State the null and alternate hypotheses. Explain whether your test will be left, right, or two-tailed.
7. In one state, the mean time served in prison by convicted burglars is 18.7 months. A researcher would like to perform a hypothesis test to determine whether the mean amount of time served by convicted burglars in her hometown is different from 18.7 months. She takes a random sample of 11 such cases from court files in her home town and finds that = 21.4 months and s = 7 months. Use a 5% significance level to perform the test. Assume normally distributed population. Perform critical-value (classical) test. Be sure to identify the null and alternate hypotheses and interpret your results. a) Hypotheses: b) Test statistic: c) Critical-value: d) Hypothesis test conclusion and interpretation:
In a certain school district, it was observed that 29% of the students in the element schools were classified as only children (no siblings). However, in the special program for talented and gifted children, 130 out of 373 students are only children. The school district administrators want to know if the proportion of only children in the special program is significantly different from the proportion for the school district. Test at the a = 0.05 level of significance. What is the hypothesized population proportion for this test? P =0.34 (Report answer as a decimal accurate to 2 decimal places. Do not report using the percent symbol) Based on the statement of this problem, how many tails would this hypothesis test have? one-tailed test two-tailed test Choose the correct pair of hypotheses for this situation: (C) (В) (A) Ho: p 0.29 Ho:p 0.29 Ho:p 0.29 H p 0.349 Ha p (F) (E) 0.349 (A) (B) (C) (D) (E) (F) N a e W
A simple random sample of 10 pages from a dictionary is obtained. The numbers of words defined on those pages are found, with the results n=10, x=65.9 words, s=16.4 words. Given that this dictionary has 1423 pages with defined words, the claim that there are more than 70,000 defined words is equivalent to the claim that the mean number of words per page is greater than 49.2 words. Use a 0.10 significance level to test the claim that the mean number of words per page is greater than 49.2 words. What does the result suggest about the claim that there are more than 70,000 defined words? Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Assume that the population is normally distributed. What are the null and alternative hypotheses? A. H0: μ>49.2 words H1: μ<49.2 words B. H0: μ=49.2 words H1: μ>49.2 words C. H0: μ=49.2 words H1: μ<49.2…
In the past, the time for Jeff's journey to work had mean 45.7 minutes and standard deviation 5.6 minutes. This year he is trying a new route. In order to test whether the new route has reduced his journey time, Jeff finds the mean time for a random sample of 30 journeys using the new route. He camies out a hypothesis test at the 2.5% significance level. Jeff assumes that, for the new route, the joumey time has a nomal distribution with standard deviation 5.6 minutes. (a) State appropriate null and alternative hypotheses for the test. (b) Determine the rejection region for the test.

Suppose a recent study of Trucks and SUVs gave an average fuel efficiency of 19.2 mpg for Trucks and 21.4 mpg for SUVs. The sample standard deviation for Trucks was 3.2 mpg and 2.8 mpg for SUVs. These results were based on samples of 35 Trucks and 39 SUVs. At the 1% significance level, can we conclude that, on average, SUVs have better fuel efficiency than Trucks? Clearly state the null and alternative hypotheses, use the critical value approach (draw a detailed picture), and write out a detailed conclusion. Organize: Hypotheses: Detailed picture: Detailed conclusion:
In a previous poll, 29 % of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Suppose that, in a more recent poll, 303 of 1113 adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under the age of 18 who eeat dinner together seven nights a week has decreased? Use the a 0.01 significance level. Because npo(1-PO) 10 and thee sample size is greater than 5% of the population size, and the sample can be reasonably assumed to be random the requirements for testing the hypothesis are not satisfied (Round to one decimal place as needed.)
