- Ten people went on a diet for a month. The weight losses experienced (in pounds) are given below. The negative weight loss is a weight gain. Test the hypothesis that the mean weight loss was more than 0, using a significance level of 0.05. Assume the population distribution is Normal. 3, 7, 10, 0, 4, 7, 5, 5, 1, and - 2 O Determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho: H0 OF. Ho: H=0 The test statistic is (Round to two decimal places as needed.) The p-value is (Round to three decimal places as needed.) Interpret the results of the test. Since the p-value is less than or equal to the significance level, reject Ho. There is sufficient evidence to conclude that the population mean is more than 0 pounds at a significance level of 0.05.A data set lists earthquake depths. The summary statistics are n 600, x 4.73 km, s 4.39 km. Use a 0.01 significance level to test the claim of a seismologist that these earthquakes are from a population with a mean equal to 4.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.

In each case, use the one-mean t-test to perform the required hypothesis test at the 5% significance level. x = 21, s = 4, n = 32, H0: μ = 22, Ha: μ<22Choose one word that fits the sentence: Based on the P-value, there is or is not sufficient evidence at a significance level of 0.01 to warrant rejection of or support the claim that for 7 AM for body temperatures of females, the mean is less than 98.6 F.The corrosive effects of various soils on coated and uncoated steel pipe was tested by using a dependent sampling plan. The data collected are summarized below, where d is the amount of corrosion on the coated portion subtracted from the amount of corrosion on the uncoated portion. Does this random sample provide sufficient reason to conclude that the coating is beneficial? Use ? = 0.01 and assume normality. n = 36, Σd = 227, Σd2 = 6244(a) Find t.

A charter school wants to know if their students have an average IQ that is higher than the population average. They take a random sample of 25 students and find a mean IQ of 108 with a standard deviation of 21. Use a 5% significance level. What is the P value with work?
