Consider the following hypothesis test: Ho:ps 0.67 Ha: p> 0.67 The p-value is equal to 0.012. Use a = 0.01. The conclusion is: Select one: O a. We accept Ho and we conclude thatp<0.67. O b. We reject Ho and we conclude that p > 0.67. O c. We accept Ho and we conclude that p > 0.67. d. We reject Ho and we conclude that p <0.67.

The average American consumes 85 liters of alcohol per year. Does the average college student consume less alcohol per year? A researcher surveyed 13 randomly selected college students and found that they averaged 82.1 liters of alcohol consumed per year with a standard deviation of 23 liters. What can be concluded at the the a = 0.10 level of significance? You may assume the data are normally distributed.

For the following hypothesis test: HO: m ≤ 14 HA: m >14 a: 0.01 with n = 38, o = 9, and x = 16, which of the following is TRUE? Select one: a. reject null hypothesis and conclude that the mean is equal to or less than 14 O b. fail to reject null hypothesis and conclude that the mean is equal to or less than 14 c. reject null hypothesis and conclude that the mean is greater than 14 d. fail to reject null hypothesis and conclude that the is greater than 14

Before the furniture store began its ad campaign, it averaged 222 customers per day. The manager is investigating if the average is smaller since the ad came out. The data for the 14 randomly selected days since the ad campaign began is shown below. Round your mean and standard deviation to three decimal places when doing these calculations. 224, 211, 206, 206, 232, 189, 222, 197, 220, 210, 212, 213, 208, 189 Download CSV Assuming that the distribution is normal, what can be concluded at the a = 0.01 level of significance?

Consider the following hypothesis test: Но : д > 170 Ha : µ < 170 The value of the test statistic z = -2.12. Find the p-value. Select one: O a. 0.0170 O b. 0.9864 O c. 0.9830 O d. 0.0136

Consider the following hypothesis test: Но : р 116 The value of the test statistic z = 1.12. Find the p-value. Select one: O a. 0.1131 O b. 0.1314 O c. 0.8869 O d. 0.2262 O e. 0.2628 O f.0.8686

Describe type I and type II errors for a hypothesis test of the indicated claim. A furniture store claims that at least 40% of its new customers will return to buy their next piece of furniture. Describe the type I error. Choose the correct answer below. OA. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is at least 0.40, but you fail to reject Ho: p20.40. OB. A type I error will occur when the actual proportion of new customers who return to buy their next piece furniture is at least 0.40, but you reject Ho: p20.40. OC. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is no more than 0.40, but you reject Ho: p ≤ 0.40. OD. A type I error will occur when the actual proportion of new customers who return to buy their next piece f furniture is no more than 0.40, but you fail to reject Ho: p ≤0.40. Describe the type II error. Choose the correct answer…
