What effect does standard deviation have on the width of the confidence interval?

Solve the problem. The probability that a football game will go into overtime is 18%. In 140 randomly selected football games, what is the mean and the standard deviation of the number that went into overtime? determine whether it is unusual to have 36 games go overtime?

Solve the problem.A bag contains 10 white, 12 blue, 13 red, 7 yellow, and 8 green wooded balls. A ball is selected from the bag, its color noted, then replaced. You then draw a second ball, note its color and then replace the ball. What is the probability of selecting one white ball and one blue ball?  The probability of selecting one white ball and one blue ball is [answer1] (Round to the nearest ten-thousandth.)

Determine the critical value zα/2 that corresponds to the given level of confidence.92% (Round to 2 decimal places)

Find the critical value.  Find the t-value such that the area in the right tail is 0.05 with 34 degrees of freedom.

Suppose you sell sandwiches at a deli store.  A review of your sales transactions reveals that 73.5% of your customers will choose turkey breast sandwiches, and the rest will choose some other sandwich.

Provide an appropriate response. A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than examine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial assistance. Use a 95% confidence interval to estimate the true proportion of students on financial aid. Express the answer in the form

Provide an appropriate response.Find the critical t-value that corresponds to 90% confidence and n = 21. (Round to 3 decimal places)
