A sample of scores has a mean of M = 20, a median of 28, and a mode of 29. What is the most likely shape for the sample distribution? symmetrical positively skewed negatively skewed cannot be determined from the information given

Red Blood Cell Count: A simple random sample of 300 adult males is taken to measure the red blood cell count (in cells per microliter). Use a significance level of 0.01 to test the claim that the sample has a mean less than the population mean (μ = 5.4 million cells per microliter). Does the sample have a normal distribution? Explain why. Does the result suggest that the male sample has a red blood cell count below 5.4 million cells per microliter? Determine the descriptive statistics of the sample. State the statistical hypotheses: H0 and HA. Determine the α Is this test one or two tailed? What statistical conclusion did you reach regarding the question being evaluated?

A survey conducted between February 25 and March 10, 2002, asked a random sample of n = 2,105 adult Americans, "Do you favor or oppose scientific experimentation on the cloning of human beings?" The responses and the percentages of adults that selected them were as follows: Favor (13%), Oppose (72%), Don't know or Refused to answer (15%). (a) What is the approximate margin of error (as a proportion) for this survey? (Round your answer to three decimal places.)   (b) Find approximate 95% confidence intervals for the proportion and the percentage of adult Americans who would say they favor this experimentation. (Round your proportions to three decimal places and your percentages to one decimal place.) proportion _ , _ percentage _ , _ %
