A simple random sample of size n = 40 is drawn from a population. The sample mean is found to be 103.7, and the sample standard deviation is found to be 20.4. Is the population mean greater than100 at the x = 0.10 level of significance?Determine the null and alternative hypotheses.Ho:H₁:Compute the test statistic.=(Round to two decimal places as needed.)Determine the P-value.The P-value is . (Round to three decimal places as needed.)What is the result of the hypothesis test?the null hypothesis because the P-value isthe level of significance. At the α = 0.10 level of significance, the population mean

Claim: The mean systolic blood pressure of all healthy adults is less than than 120 mm Hg. Sample data: For 276 healthy adults, the mean systolic blood pressure level is 119.61 mm Hg and the standard deviation is 14.88 mm Hg. The null and alternative hypotheses are Ho: μ = 120 and H₁: μ< 120. Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.) C

Use the scores to compare the given values. Based on sample data, newborn males have weights with a mean of 3278.8 g and a standard deviation of 986.2 g. Newborn females have weights with a mean of 3026.9 g and a standard deviation of 549.2 g. Who has the weight that is more extreme relative to the group from which they came: a male who weighs 1500 g or a female who weighs 1500 g? Since the Z score for the male is Z =______ and the z score for the female is z=______, the _______ has the weight that is more extreme. (Round to two decimal places.)
Medical Operations The director of a medical hospital feels that her surgeons perform more operations per year than the national average of 211. She selected a random sample of 15 surgeons and found that the mean number of operations they performed was 213.2. The standard deviation of the sample was 3.8. Is there enough evidence to support the director's feelings at =α0.05? Assume that the population is approximately normally distributed. Use the critical value method and tables. State the hypotheses and identify the claim. H0: Is a claim or not a claim H1: is a claim or is not a claim Find the critical value: Compute the test value: Make the decision Summarize the results. There is or is not enough evidence to support the claim.
