Whichof the following represents the best conclusion?A. The data provides sufficient evidence that the proportion of red outcomes is greater than 25%B. The data does not provide sufficient evidence that the proportion of red outcomes is greaterthan 25%

According to a recent study in New York, 15% of shoppers are unfairly being charged sales tax in non-taxable items.  Mr. Hypothesis feels this proportion is too low.  He tests his belief by conducting a survey of 200 random shoppers. Which of the following would be the alternate hypothesis?   a. The percent of shoppers unfairly being charged sales tax on non-taxable items  < .15   b. The percent of shoppers unfairly being charged sales tax on non-taxable items > .15   c. The percent of shoppers unfairly being charged sales tax on non-taxable items = .15

A marriage counselor has traditionally seen that the proportion p of all married couples for whom her communication program can prevent divorce is 80%. After making some recent changes, the marriage counselor now claims that her program can prevent divorce in more than 80% of married couples. In a random sample of 215 married couples who completed her program, 180 of them stayed together. Based on this sample, is there enough evidence to support the marriage counselor’s claim at the 0.05 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. A. State the null hypothesis Hoand the alternative hypothesis H1. Ho: H1: B. Find the value of the test statistic. (Round to three or more decimal places.) C. Find the critical value. (Round to three or more decimal places.) D. Is there enough evidence to support the marriage counselor's claim that the proportion of married couples for whom her program…

(c) Calculate the test statistic. d) Decide whether to reject or fail to reject the null hypothesis. Then interpret the decision in the context of the original claim.

A marriage counselor has traditionally seen that the proportion p of all married couples for whom her communication program can prevent divorce is 79%. After making some recent changes, the marriage counselor now claims that her program can prevent divorce in more than 79% of married couples. In a random sample of 250 married couples who completed her program, 205 of them stayed together. Based on this sample, is there enough evidence to support the marriage counselor's claim at the 0.05 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H and the alternative hypothesis H₁. H₂ : D H₁ : 0 (b) Determine the type of test statistic to use. (Choose one) (c) Find the value of the test statistic. (Round to three or more decimal places.) 0 (d) Find the p-value.

A marriage counselor has traditionally seen that the proportion p of all married couples for whom her communication program can prevent divorce is 77%. After making some recent changes, the marriage counselor now claims that her program can prevent divorce in more than 77% of married couples. In a random sample of 215 married couples who completed her program, 167 of them stayed together. Based on this sample, is there enough evidence to support the marriage counselor’s claim at the 0.10 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.)   (a) State the null hypothesis H0 and the alternative hypothesis H1. H0: H1: (b) Determine the type of test statistic to use.   ▼(Choose one)   (c) Find the value of the test statistic. (Round to three or more decimal places.)   (d) Find the p-value. (Round to three…

You are a process engineer for a company that manufactures widgets. A particular machine at your company has some downtime during the day on 36.5% of days. You decided to make some changes to how the machine is calibrated in an attempt to reduce downtime. 63 days after your changes were implemented, you find that the machine had some downtime during the day on 31.0% of days. Conduct a hypothesis test to determine if the proportion of days that the machine has downtime has decreased from before, with a= 0.1. * Using this information, what is the p in your analysis? Note: 1- Only round your final answer. Enter your final answer with 2 decimal places.
