4. Two populations are surveyed with simple random samples. A sample of size nis used for population I, which has a population standard deviation ; a sample ofsize 2 2n is used for population II, which has a population standard deviationσ-= 2σι. Ignoring finite population corrections, in which of the two sampleswould you expect the estimate of the population mean to be more accurate?

Here given that one sample is drawn from a population with standard deviation σ1 and sample size of…

For men heights are normally distributed with a mean of 69 inches and a standard deviation of 2.8 inches. If samples of 25 men are selected at random from the population, would the average height found for each sample be more or less varied than the individual measurements taken for each man?B
An IQ test is designed so that the mean is 100 and the standard deviation is 10 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 95% confidence that the sample mean is within 2 IQ points of the true mean. Assume that σ=10 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation.

A variable of two populations has a mean of 30 and a standard deviation of 18 for one of the populations and a mean of 30 and a standard deviation of 32 for the other population. Complete parts (a) through (c). a. For independent samples of size 9 and 16, respectively, find the mean and standard deviation of X₁ -X₂. (Assume that the sampling is done with replacement or that the population is large enough.) The mean of X₁ -X₂ is. (Type an integer or a decimal. Do not round.) The standard deviation of X₁-X₂ is (Round to four decimal places as needed.) b. Must the variable under consideration be normally distributed on each of the two populations for you to answer part (a)? Choose the correct answer below. OA. No, the variable does not need to be normally distributed for the formulas for the mean and standard deviation of x₁-x₂ to hold as long as the sample sizes are large enough, as long as the sampling is done with replacement. B. No, the formulas for the mean and standard deviation of…
