A simple random sample of size n = 15 is drawn from a population that is normally distributed. The sample mean is found to be x = 21.1 and the sample standard deviation is found to be s = 6.3. Determine if the population mean is differentfrom 24 at the x = 0.01 level of significance. Complete parts (a) through (d) below.(a) Determine the null and alternative hypotheses.Ho: μH₁ μ(b) Calculate the P-value.= 24#24P-value = 0.096(Round to three decimal places as needed.)(c) State the conclusion for the test.A. Reject Ho because the P-value is less than the x = 0.01 level of significance.B. Do not reject Ho because the P-value is less than the α = 0.01 level of significance.C. Do not reject Ho because the P-value is greater than the α = 0.01 level of significance.D. Reject Ho because the P-value is greater than the α = 0.01 level of significance.(d) State the conclusion in context of the problem.Theresufficient evidence at the α = 0.01 level of significance to conclude that the population mean is different from 24.

A sample of 34 observations is selected from a normal population. The sample mean is 45, and the population standard deviation is 5. Conduct the following test of hypothesis using the 0.02 significance level. H0: μ = 46 H1: μ ≠ 46 Is this a one- or two-tailed test? multiple choice 1 One-tailed test Two-tailed test What is the decision rule? multiple choice 2 Reject H0 if −2.326 < z < 2.326 Reject H0 if z < −2.326 or z > 2.326 What is the value of the test statistic? (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.)
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 180 74 В 150 69 95 63 70 56 70 40 F 35 28 (a) The estimated regression equation for this data is ý = 25.870 + 0.291x, 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.

An IQ test is designed so that the mean is 100 and the standard deviation is 13 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 95% confidence that the sample mean is within 5 IQ points of the true mean. Assume that o = 13 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is. (Round up to the nearest integer.) Would it be reasonable to sample this number of students? No. This number of IQ test scores is a fairly small number. No. This number of IQ test scores is a fairly large number. Yes. This number of IQ test scores is a fairly small number. Yes. This number of IQ test scores is a fairly large number.

A sample is randomly selected from a population with a mean of μ = 50, and a treatment is administered to the individuals in the sample. After treatment, the sample is found to have a mean of M = 56 with a standard deviation of s = 8. Which test is most appropriate to determine if there is a difference between the means? z-score test single-sample t-test independent samples t-test related-samples t-test
A random sample of 85 eighth grade students' scores on a national mathematics assessment test has a mean score of 276. This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 270. Assume that the population standard deviation is 31. At α=0.08, is there enough evidence to support the administrator's Claim? 1.Decide whether to reject or fail to reject the null hypothesis.

A random sample of n1 = 49 measurements from a population with population standard deviation ?1 = 3 had a sample mean of x1 = 9. An independent random sample of n2 = 64 measurements from a second population with population standard deviation ?2 = 4 had a sample mean of x2 = 11. Test the claim that the population means are different. Use level of significance 0.01.
