I randomly chose 50 textbooks off the shelves in the WSU bookstore. I found that their average cost was $87.42 with a standard deviation of $13.56. I want to perform a test of hypothesis to determine if the average cost of textbooks is greater than $80. What is the appropriate null hypothesis? O H= 80 O p> 80 O u< 80 O u2 80 p= 87.42 O p> 87.42 O u< 87.42 O us 87.42

Among private universities in the United States, the mean ratio of students to professors is 35.2 (i.e., 35.2 students for each professor) with a standard deviation of 8.8. Suppose a random sample of 50 universities is selected and the observed mean student-to-professor ratio is 38. Is there evidence that the reported mean ratio actually exceeds 35.2? Use  = 0.05 and conduct the appropriate hypothesis test. ( See attached picture )
2. A scoop is manufactured to put exactly 4.5 ounces of mashed potatoes on a plate per scoop. When you test the scoop 25 times, you notice that you scoop an average of 4.9 ounces of mashed potatoes per scoop, with a sample standard deviation of 1.2 ounces. Can we say that the amount of mashed potatoes scooped is significantly different from the claim of the scoop manufacturer? What type of hypothesis test is this? Group of answer choices 2 proportion z-test t-test 1 proportion z-test 2 sample t-test
A quiz related to digital knowledge was conducted. The quiz had 10 questions and covered topics such as the purpose of browser cookies, phishing scams, and privacy policies. The survey was given to 50 people. The mean score is 4.1 with a standard deviation of 2.6. We want to know if the data provide evidence that the mean score in the population is lower than 5. We will use alpha = 0.05 to make our decision. What is the null hypothesis for this question? Group of answer choices a. The proportion of people who pass the test is 5. b. The mean test score of the population is 5. c. The mean test score of the 50 people who took the test is 5. d.The standard deviation is 2.6
According to the American Time Use Survey, the typical American spends 183 minutes per day watching television. A college dean wondered if college students were different. He conducted a survey of 50 college students and found they had a mean of 165 minutes per day with a standard deviation of 72. To test this hypothesis, find P-value and rind to the nearest thousandth. Using the a=0.05, write a conclusion for the hypothesis test for question above, state whether or not you are rejecting hypothesis and what the hypothesis is in words, write a sentence that the researcher could share with colleagues without using technical terms for statistics
65 homeless people in San Jose were asked their age. The sample mean age was 33.2 years. Let x be a random variable representing ages of homeless people in San Jose. Assume that x has a normal distribution and o = 7.3 years. Do the data indicate that the mean age of the population of homeless people in San Jose is less than 35 years old? Use a = 0.05. Identify the following in your answer. 1. Identify the null hypothesis Ho and alternate hypotheses H, for the problem. 2. Identify the sample statistic, test statistic, p-value and calculator key used: Sample Statistic (sample mean) (Stated in problem) = Test Statistic (z) (Round to two decimal places) %3D P-value: (Round to four decimal places) = Calculator key used: 3. Identify the significance level and determine if you reject or fail to reject the null hypothesis. significance level = Do you reject or fail to reject Ho ? 4. State your conclusion.

The Boston Bottling company distributes cola in cans labeled 12 oz. The Bureau of Weights and Measures randomly selected 24 cans, measured their contents, and obtained a sample mean of 11.82 oz and a sample standard deviation of 0.38 oz.

The coach of a very popular men’s basketball team claims that the average distance the fans travel to the campus to watch a game is 35 miles. The team members feel otherwise. A sample of 16 fans who travel to games was randomly selected and yielded a mean of M= 36 miles and s= 5 miles. Test the coach’s claim at the 5% (.05) level of significance. one-tailed or two-tailed test: State the hypotheses: df= tα or t value for the critical region = sM = t (test statistic)= Decision:
A discount airline allows staff 36.0 minutes between flights to clean the aircraft interior. The aircraft workers union claims that that average time that it takes to this cleaning is more than 36.0 minutes. They want to carry out a hypothesis test. They take a random sample n = 40 flights and time how long it takes to carry out the cleaning. They find that the sample mean is 36.66 minutes and the sample standard deviation is 5.56 minutes. Calculate the test statistic for this test and enter your answer below. Give your answer to 2 decimal places.
The cost of a car is $30k at Joe's Garage. You cant to see if the cost is lower at Pete's Garage. To test, you collect data from 64 buyers who recently bought cars. The average of your sample is $29,760, with a sample standard deviation of $7,450. Using this data to perform the hypothesis test with H0: u=30,000 vs H0:u<30,000, what is the p-value of this test, and what is the conclusion of this test at the a=.05 level?
The mean number of eggs per person eaten in the United States is 266. Do college students eat a different number of eggs than the average American? The 61 college students surveyed averaged 285 eggs per person and their standard deviation was 72.6. What can be concluded at the a= 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: v Select an answer H.: vSelect an answer c. The test statistic ? (please show your answer to 3 decimal places.) d. The p-value = e. The p-value is ? f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) a O The data suggest that the sample mean is not significantly different from 266 at a = 0.10, so there is statistically insignificant evidence to conclude that the sample mean number of eggs consumed by college students per year is different from 285. O The data suggest that the…
