ET ANSWER. Write the word or phrase that best completes each statement on answers the question. indicated claim about the means of twe populations. Assume that the two samples are independent siempl qual. Use the traditional method or P-value method as indicated est the random sampl ples selected from normally distributed populations. Do not assunme that the pepalation Mandard deviation types of flares are tested and their burning times (in minutes) are recorded. The summary statisties are given below Brand X n-35 Brand Y 19.4 min 15.1 min s -1.4 min 0.8 min Use a 0.05 significance level to test the claim that the two samples are from populations with the same mean. Use the traditional method of hypothesis testing Solve the problem. 7) A population consists of these values: 3, 5, 8, 14, 17. Find the mean, u, and standard deviation, o, of the population. List all samples of size n - 2 that are obtained without nt. Find the population of all values of x by finding the mean of each sample that listed. Find the mean means by using the formulas: you and standard deviation o for the population of sample Test the given claim. Use the P-value method or the traditional method as indicated. Identify the mull hypothesis alternative hypothesis, test statistic, critical valuels) or P-value, conclusion about the null hypothesis, and final 8) A simple random sample of 15-year old boys from one city is obtained and their weights 5 (in pounds) are listed below. Use a 0.01 significance level to test the claim that these sample weights come from a population with a mean equal to 150 lb. Assume that the standard deviation of the weights of all 15-year old boys in the city is known to be 16.4 lb. Use the conclusion that addresses the original claim. traditional method of testing hypotheses. 149 140 161 151 134 189 157 144 175 127 164 Use the given information to find the P-value. Also, use a 0.0s significance level and state the conclusion about the nall hypothesis (reject the null hypothesis or fail to reject the null hypothesis). A) 0.0764; fail to reject the null hypothesis C) 0.1528; fail to reject the null hypothesis B) 0.1528, reject the null hypothesis D) 0.0764; reject the null hypothesis 9) The test statistic in a right-tailed test is z -1.43 10) Identify the given random variable as being discrete or continuous B) Continuous 10) The number of phone calls between New York and California on Thanksgiving day A) Discrete
