Sales can vary considerablyon the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same 12 days,chosen at random. She records the sales (in dollars) for each store on these days, as shown in the table below.DayStore 1Store 2144HzDifference(Store 1 - Store 2)Send data to calculatorH :O01TTExplanation233116Check117V23553ننا4394 503146 275 64454855816(a) State the null hypothesis Ho and the alternative hypothesis H₁.0784 505727209 119 -141 -96 57O Search7428N008853723920536677 130 - 16110Based on these data, can the owner conclude, at the 0.05 level of significance, that the mean daily sales of the two stores differ? Answer this question byperforming a hypothesis test regarding μ (which is μ with a letter "d" subscript), the population mean daily sales difference between the two stores.

Consider the following data on price ($) and the overall score for six stereo headphones tested by a certain magazine. The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). Brand Price ($) Score A 180 76 B 150 69 95 59 70 58 E 70 42 35 26 (a) The estimated regression equation for this data is ý = 24.599 + 0.304x, where x = price ($) and y = overall score. Does the t test indicate a significant relationship between price and the overall score? Use a = 0.05. State the null and alternative hypotheses.

A sample mean, sample size, and population standard deviation are provided below. Use the one-mean z-test to perform the required hypothesis test at the 5% significance level. x=33, n=11, σ=5, H0: μ=30, Ha: μ>30 The test statistic is z=_____________ (Round to two decimal places as needed.) The P-value is ___________. (Round to four decimal places as needed.) ____________ (Do not reject, Reject) the null hypothesis. The data _____________ (do not provide, provide) sufficient evidence to conclude that the mean is __________________ (equal to 30, greater than 30, less than 30. not equal to 30.)
Use the given information to find the P-value. Also, use a 0.05 significance level and state theconclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis).With H1: p (does not equal) 0.377 the test statistic is z = 3.06.
You are conducting a hypothesis test where the null hypothesis is that true population mean is less than or equal to 180. Your test will be at the 0.10 significance level. You take a sample of size n=60, and find that the sample average is 185, and the STANDARD ERROR is 15. What is the value of your test statistic? (Please answer to two decimal places. ex: 5.43)

Test the claim that the proportion of men who own cats is smaller than 90% at the .01 significance level. The test is based on a sample of 25 people, in which 84% of the sample owned cats. The null and alternative hypothesis would be: Ho:p = 0.9 H1:p < 0.9 The test is left tailed. What is the test statistic and critical value? (to 2 decimal places)
Test the claim that the proportion of men who own cats is smaller than 60% at the .01 significance level. Based on a sample of 100 people, 59% owned catsThe test statistic is: (to 2 decimals)The critical value is: (to 2 decimals)
(Multiple Choice) Use the given information to find the P-value. Use a 0.05 level of significance and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a two-tailed test is z=0.83. (a) 0.2033; reject the null hypothesis (b) 0.4065; fail to reject the null hypothesis (c) 0.2033; fail to reject the null hypothesis (d) 0.4065; reject the null hypothesis
