The is a nonparametric test that uses ranks of sample data from two independent populations to test the null hypothesis that the two independent samples come from populations with equal medians.

- K Describe type I and type II errors for a hypothesis test of the indicated claim. A furniture store claims that at least 75% 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 piece furniture is no more than 0.75, but you reject Ho: ps 0.75. OB. A type I error will occur when the actual proportion of new customers who return. piece of furniture is at least 0.75, but you reject Ho: p20.75. buy their next buy their next OC. A type I error will occur when the actual proportion of new customers who return to buy their next piece furniture is at least 0.75, but you fail to reject Ho: p20.75. OD. A type I error will occur when the actual proportion of new customers who return buy their next piece of furniture is no more than 0.75, but you fail to reject Ho: p≤0.75. Describe the type Il error. Choose the correct answer below. OA.…H0: =, >, <, or ≠ _______________ year (s). H1: =, >, <, or ≠ _________________ year (s). Since the P-value is less than or equal to, or more than or equal to the significance level, reject or do not reject the null hypothesis. There is or is not sufficient evidence to support the claim that actress are generally younger when they won the award than actors. Since the confidence interval contains only zero, positive number values, or only negative number values, reject or warrent rejection of the null hypothesis.Decide whether to reject or fail to reject the null hypothesis. Z (right - tailed test), a = 0.05 Zcomputed = 1.42
- (06.05 MC) Which of the following is a TRUE statement about hypothesis testing? Group of answer choices The probability of a Type I error plus the probability of a Type II error always equals one. The power of a test concerns its ability to detect a null hypothesis. If there is sufficient evidence to reject a null hypothesis at the 5% level, then there is sufficient evidence to reject it at the 10% level. Whether to use a one-sided or a two-sided test is typically decided after the data are gathered. If a hypothesis test is conducted at the 1% level, there is a 1% chance of rejecting the null hypothesis.Answer all A, B, C and D questionsState the null and alternative hypothesis. H0: ≠, >, =, or < ____________ (Type an integers or decimals. Do not round) H1: ≠, >, ≤, <, ≥, or = __________ (Type an integers or decimals. Do not round)
- Hypothesis Testing Review For each problem below, simply identify the null and alternative hypotheses. Use appropriate notation/symbols. You do not have to run any hypothesis tests, although it's good practice and I'll post answers for all of them. 1) A simple random sample of 44 men from a normally distributed population results in a standard deviation of 10.7 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute. 2) In 1997, a survey of 880 households showed that 145 of them use e-mail. Use those sample results to test the claim that more than 15% of households use e-mail. Use a 0.05 significance level.uppose you reject the null hypothesis H0: μ = 101. It turns out the population mean is actually equal to 101. You have made a Group of answer choices Type I and Type II errors the correct decision Type II error Type I errorIn a hypothesis test the p-value is calculated to be 0.56. Which of the following is the most reasonable decision? Reject the null hypothesis. Accept the null hypothesis. Reject the alternative hypothesis. Fail to reject the null hypothesis.
