University graduates have a mean job search time of 38.1 weeks, with a standard deviation of 10.1 weeks. The distribution of job search times is not assumed to be symmetric. Between what two search times does Chebyshev's Theorem guarantee that we will find at least 89% of the graduates? Round your answers to the nearest tenth.
The mean for life expectancy is 47.6 for White people who were born in 1900 and 33.0 for non-white people. Suppose you randomly sample the death records for people born in 1900 in a certain country. Of the 124 white people, the mean life span is 45.3 years and the standard deviation is 12.7 years. 82 of the non-white people have a mean life span of 34.1 and a standard deviation of 15.6 years. A hypothesis test is needed to see if the mean is the same for both countries for White and Non-White people. Is this a right, left or two-tailed test.
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).
A theory predicts that the mean age of stars within a particular type of star cluster is 3.5 billion years, with a standard deviation of .7 billion years. (Their ages are approximately normally distributed.) You use a computer to randomly select the coordinates of 40 stars from the catalog of known stars of the type you're studying and you estimate their ages. You find that the mean age of stars in your sample is 3.7 billion years. Suppose (before collecting your sample) that you think the mean age of stars is actually greater than the 3.5 billion year-old claim, and that this would lend support to an alternative theory about how the clusters were formed. A. To test whether the population mean is greater than 3.5 billion years, what would your null and alternative hypotheses be? B. Explain why you can't use the p-value from question 2c to reach a conclusion on this significance test: (question from 2c that I posted on another chegg question is: C.

Assume that male and female heights are both normally distributed with a male average of 69.1 inches with standard deviation of 2.8 inches, and a female average of 64.0 inches with standard deviation 2.5 inches. If a male and female go out on a date, what is the probability that the female is taller than the male? Show work.

A recent study of the lifetimes of cell phones found the average is 24.3 months. The standard deviation is2.6 months. If a company provides its 36 employees with a cell phone, find the probability that the mean lifetime of these phoneswill be less than 23.2 months. Assume cell phone life is a normally distributed variable, the sample is taken from a largepopulation and the correction factor can be ignored. Round the final answer to at least four decimal places and intermediateZ -value calculations to two decimal places.
The mean daily production of a herd of cows is assumed to be normally distributed with a mean of 39 liters, and standard deviation of 6.2 liters.A) What is the probability that daily production is between 20.8 and 28.4 liters? Do not round until you get your your final answer.Answer= (Round your answer to 4 decimal places.)Warning: Do not use the Z Normal Tables...they may not be accurate enough since WAMAP may look for more accuracy than comes from the table.
