You may need to use the appropriate appendix table or technology to answer this question. In 2012, seventy percent of Canadian households had an internet connection. A sample of 370 households taken in 2013 showed that 76% of them had an internet connection. We are interested in determining whether or not there has been a significant increase in the percentage of the Canadian households that have internet connections. (a) State the null and alternative hypotheses to be tested. (Enter != r as needed. Let p be the proportion of all Canadian households with internet connections.) Ho: H₂: (b) Compute the test statistic. (Round your answer to two decimal places.) (c) The null hypothesis is to be tested at the 5% level of significance. Determine the critical value(s) for this test. (Round your answer(s) to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic s test statistic 2 (d) What do you conclude? Do not reject Ho. We can conclude that there has been a significant increase in the percentage of the Canadian households that have internet connections. Do not reject Ho. We cannot conclude that there has been a significant increase in the percentage of the Canadian households that have internet connections. Reject Ho. We can conclude that there has been a significant increase in the percentage of the Canadian households that have internet connections. Reject Ho. We cannot conclude that there has been a significant increase in the percentage of the Canadian households that have internet connections.

tab A study showed that 62% of supermarket shoppers believe supermarket brands to be as good as national name brands. To investigate whether this result applies to its own product, the manufacturer of a national name-brand ketchup asked a sample of shoppers whether they believed that supermarket ketchup was as good as the national brand ketchup. (a) Formulate the hypotheses that could be used to determine whether the percentage of supermarket shoppers who believe that the supermarket ketchup was as good as the national brand ketchup is less than 62%. Ho: P = 0.62 H₂: P = 0.62 Ho: p≥ 0.62 H₂: P 0.62 H₂: p ≤ 0.62 Ho: p ≤ 0.62 H₂: p > 0.62 (b) If a sample of 100 shoppers showed 49 stating that the supermarket and was as good as the national brand, what is the p-value? Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value = (c) At a = 0.05, what is your conclusion? Do not reject Ho. There is…

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 hypothesis

Suppose that in a random selection of 100 colored​ candies, 22​% of them are blue. The candy company claims that the percentage of blue candies is equal to 28​%. Use a 0.01 significance level to test that claim.       Identify the null and alternative hypotheses for this test. Choose the correct answer below.     A. H0​: p≠0.28 H1​: p=0.28   B. H0​: p=0.28 H1​: p>0.28   C. H0​: p=0.28 H1​: p<0.28   D. H0​: p=0.28 H1​: p≠0.28 Identify the test statistic for this hypothesis test.   The test statistic for this hypothesis test is nothing. ​(Round to two decimal places as​ needed.) Identify the​ P-value for this hypothesis test.   The​ P-value for this hypothesis test is nothing. ​(Round to three decimal places as​ needed.) Identify the conclusion for this hypothesis test.     A. Reject H0. There is not sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 28​%   B. Reject H0.…

3. A claim is made that the proportion of college students who have Netflix accounts is 0.85. Noah believes this claimed value is too high. He is able to survey a random sample of 240 college students, and he finds that the sample proportion who have Netflix accounts is 0.82. Noah proceeds to use this data to conduct a hypothesis test. Based on this information, which one of the following statements is correct? A. The p-value will be smaller than 0.01 but larger than 0. B. The p-value will be between 0.01 and 0.05. C. The p-value will be between 0.05 and 0.10. D. The p-value will be larger than 0.10.

in this exercise, we are conducting many hypothesis tests to test a claim. assume that the null hypothesis is true. if 1100 tests are conducted using a significance level of 5. approximately how many of the tests will incorrectly significance

A publisher reports that 67% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 250 found that 62% of the readers owned a particular make of car. State the null and alternative hypotheses. what is HO and HA ?

A survey asked 1578 US residents: “Do you think the use of marijuana should be made legal, or not?”. 61% of respondents said it should be made legal. A newscaster said of this story that “a majority of Americans think marijuana should be legalized”. Use hypothesis testing to see if this newscaster’s statement is justified.

Question 6 In this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 100 tests are conducted using a significance level of 5%, approximately how many of the tests will incorrectly find significance?Enter your answer in accordance to the question statement of the tests will find significance.

Could someone explain how to solve this problem? I've been stuck on this one for quite a while, thanks!
