Suppose the coffee industry claimed that the average adult drinks 1.7 cups of coffee per day. To test this claim, a random sample of 50 adults was selected, and their average coffee consumption was found to be 1.85 cups of daily coffee consumption per day is 0.5 cups. Using a = 0.10, complete parts a and b below. a. Is the coffee industry's claim supported by this sample? Determine the null and alternative hypotheses.

A coin-operated drink machine was designed to discharge a mean of 9 ounces of coffee per cup. Suppose that we want to carry out a hypothesis test to see if the true mean discharge differs from 9. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. Ho: 0 H1: 0 OsO O>o O20 ?
When we test the hypothesis that the population proportions are equal, we can use the Z test for a one-sided as well as a two-sided alternative. Select one: a. False b. True C. Not sure
The one-sample ?‑statistic for a test of ?0:?=0 versus ?1:?≠0 based on ?=15 observations has the value ?=−2.138, where ?0 and ?1 are the null and alternative hypotheses, respectively. The sample size is denoted by ?. Use this ?‑table to determine which two ?-values bracket the ?-value of the test. Report your answer as listed in the given ?‑table.

Do question 7,8 and 9 only The new study also carried out a test to determine whether the population proportion of unvaccinated school children contracting winter flu was higher than the population proportion of vaccinated school children. The Z test statistic to test this belief is found to be 1.874. The corresponding p-value is 0.0305 0.1212 0.3036 0.7724 Question 7 Suppose that the new study uses a level of significance of 0.05 to test the claim in Question 6. The probability of Type I error is 0.025 0.05 0.95 0.975 Question 8 Based on previous studies of school children who were vaccinated and contracted the flu, the time in hours that the flu symptoms last is assumed to follow a normal distribution with a mean of 20.7 hours and a standard deviation of 7.3 hours. The probability that a randomly selected school child has flu symptoms for more than 24 hours is 0.1628 0.3256 0.6744 0.8372 Question 9 Suppose that a random sample of 5 vaccinated school children is taken.

The owner of a fitness watch would like to determine if the mean number of steps he takes per day differs from the recommended 10,000 steps per day, using a = 0.01. He selects a random sample of 50 days with the intention of testing the hypotheses Ho:u = 10,000 steps versus Ha p # 10,000 steps where p = the true mean number of steps taken per day. Which of the following values of the alternative hypothesis would yield the greatest power to reject the null hypothesis? Ο μ-9,000 O p =9,500 O H = 10,000 Ο μ 10,500

In case of hypothesis testing in places where population variances are unknown and sample size is large (nl and n22 30), sample variances can be a good approximation of population variances. Which best describe this statement? Select one: O a. None of the choices O b. The statement is true c. The statement is false O d. Not enough data to support the statement O e. The statement is neither true nor false

By referencing past data, the group belive that more than 45% of Americans can do so. a. state the null and alternative hypotheses for testing the group's belief/ b. If the value of the test statistic is approximately 1.46, what is the conslusion (reject H0 of fail to reject H0) of the hypotesis test? with a-0.05 c. If the true balue of is 48%, did the researchers make an error? if so what type?
