A random sample of 64 rivets is taken. Consider the distribution of \( \overline{X} \), the sample mean breaking strength.(a) What is the probability that the sample mean falls between 4910 psi and 5090 psi?(b) What sample \( n \) would be necessary in order to have \( P(4980 < \overline{X} < 5020) = 0.90 \)?

Let Xi be the breaking strength of the rivet in ith machine, i=1,2,...,n. When n is large, we can…

According to a random sample taken at 12 A.M., body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.25 °F and a standard deviation of 0.67°F. Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 2 standard deviations of the mean? What are the minimum and maximum possible body temperatures that are within 2 standard deviations of the mean? ... At least of healthy adults have body temperatures within 2 standard deviations of 98.25°F. (Round to the nearest percent as needed.)

An ecologist is studying the impact of local polluted waters on the growth of alligators. The length of adult male alligators typically follows a normal distribution with a standard deviation of 2 feet. The ecologist wants to estimate the mean length of this population of alligators. Suppose she samples n alligators at random and uses the sample mean, X to as an estimator for u. a. What is the bias and variance of the estimator? (Note, these may be a function of n.) b. If n = 4, what is the probability that the estimator is within one foot of the true mean? (I.e. find P(|X – µ| < 1). c. What sample size, n, is required for the estimator to be within one foot of the true mean with 95% probability? (I.e. find the value of n that satisfies P(|X – µ| < 1) = 0.95.) d. Suppose the ecologist ends up sampling n = 9 alligators and calculates a sample mean of ī = 10.4 feet. Construct a 95% confidence interval for the population mean. e. Give an interpretation for the interval obtained in (d).
