Provide one statement AND one question about the following:
A confidence level is a percentage of a sample that indicates a certain section or range of data points that can contain a population parameter. The range itself is the confidence interval.
The larger the sample size, the smaller the width of the confidence level and the smaller the range or confidence interval. As the width of the confidence interval gets smaller, the standard error also decreases. As the confidence interval includes less points or gets smaller, the chance of error decreases because there are less data points involved.
The smaller the sample size, the larger the width of the confidence level and the larger the range or confidence interval. As the width of the confidence interval gets larger, the standard error also increases. As the confidence interval includes more data points or gets larger, the chance of error increases because there are more data points involved.
Assume that the distribution is normal. Based on the Empirical Rule, how many students scored between 57 and 93?
a survey has revealed that 75 of all college students study. it is also known that 85 of all students who study will

suppose the service time in minutes at a bank has the exponential distribution with lambda 12. use the central limit
Find the distribution of Tn, and compute E Tn and Var Tn. Remark. Customers arriving (and leaving) while the ATM is busy thus do not affect the service time.
At most, only 30 newspaper ads are possible. For every 106.7 radio ad, there must be at least two 103.1 Radio ads. Formulate the LP model to determine the number of ads in each outlet and maximize the effective audience contact.

Compute correlation loading coefficients using (a) the correlation matrix, and (b) the covariance matrix. How do the two sets of coefficients compare to each other? Are both sets equally informative? Explain (see also Exercise 3.23).

A study compared colleges that tested for drugs with colleges that did not, finding similar levels of students using drugs in each. State a potential lurking variable that could affect the results of a study.
Problem: Let (X, Y) be jointly distributed inside the ellipse given by {(x, y) : ax2 + by2 = 1}. Find the marginal densities of X and Y and the conditional densities of Y given X and X given Y. Are X and Y correlated? Are they independent?
