Marketers believe that 65.08% of adults in the U.S. own a cell phone. A cell phone manufacturer believes the proportion is different than 0.6508. 38 adults living in the U.S. are surveyed, of which, 28 report that they have a cell phone. Using a 0.01 level of significance test the claim. The correct hypotheses would be: O Ho:p < 0.6508 HA:p > 0.6508 (claim) О Но:р> 0.6508 НА:р < 0.6508 (claim) О Но:р 3 0.6508 HA:P + 0.6508 (claim) Since the level of significance is 0.01 the critical value is 2.576 and -2.576 The test statistic is: (round to 3 places) The p-value is: (round to 3 places) The decision can be made to: O reject Ho O do not reject Ho The final conclusion is that: O There is enough evidence to reject the claim that the proportion is different than 0.6508. There is not enough evidence to reject the claim that the proportion is different than 0.6508. O There is enough evidence to support the claim that the proportion is different than 0.6508. O There is not enough evidence to support the claim that the proportion is different than 0.6508.

A business owner claims that the proportion of take out orders is greater than 25%. To test this claim, the owner checks the next 250 orders and determines that 60 orders are take out orders The following is the setup for this hypothesis test: Ho :p 0.25 Ha p>0.25 In this example, the p-value was determined to be 0.643. come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%) Select the correct answer below: O The decision is to reject the Null Hypothesis. The conclusion is that there is enough evidence to support the claim. The decision is to fail to reject the Null Hypothesis. The conclusion is that there is not enough evidence to support the claim.
The US Department of Energy reported that 49% of homes were heated by natural gas. A random sample of 327 homes in Oregon found that 143 were heated by natural gas. Test the claim that proportion of homes in Oregon that were heated by natural gas is different than what was reported. Use a 10% significance level. Give answer to at least 4 decimal places. a. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) H0: H1: Based on the hypotheses, compute the following:b. Test Statistic = c. p-value = d.
