19. Assume that pulse rates of men follow a bell-shaped (normal) distribution with a mean of 74 beats per minute and a standard deviation of 12 beats per minute. a. Based upon the Empirical Rule, give an interval that contains about 95% of all such pulse rates. this has to be solved using excel functions (new versions)
- P2 given the relevant sample results. Assume the results come Use the normal distribution to find a confidence interval for a difference in proportions p from random samples. A 95% confidence interval for pı - P2 given that Pı = 0.20 with nį = 60 and P2 = 0.40 with n2 = 120 Give the best estimate for p - p2, the margin of error, and the confidence interval. Round your answer for the best estimate to two decimal...
R problem 1: The reason that the t distribution is important is that the sampling distribution of the standardized sample mean is different depending on whether we use the true population standard deviation or one estimated from sample data. This problem addresses this issue. 1. Generate 10,000 samples of size n- 4 from a normal distribution with mean 100 and standard deviation σ = 12, Find the 10,000 sample means and find the 10,000 sample standard deviations. What are the...
Suppose that you wish to test a claim about a population mean. Which distribution should be used given that the sample is a simple random sample, σ is not known, n = 15 and the population is normally distributed?
