A multiple-choice examination consists of 95 questions, each having possible choices a, b, c, and d. Approximate the probability that a student will get at most 24 answers correct if he randomly guesses at each answer. (Note that, if he randomly guesses at each answer, then the probability that he gets any one answer correct is 0.25.) Use the nomal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (If necessary, consult a list of formulas.)

The proportion of eligible voters who will vote for Shaun Spicer in the next Presidential election is assumed to be 42%. A random sample of 400 voters is drawn and reveals a sample proportion of 40%. Calculate the standard error of the proportion. Round the final answer to four decimal places.
When women were finally allowed to become pilots of fighter jets, engineers needed to redesign the ejection seats because they had been originally designed for men only. The ejection seats were designed for men weighing between 150 lb and 201 lb. Weights of women are now normally distributed. with a mean of 169 lb and a standard deviation of 45 lb. Complete parts (a) through (c) below.

Assume that when an adult is randomly selected, the probability that they do not require vision correction is 18%. If 7 adults are randomly selected, find the probability that exactly 2 of them do not require a vision correction. if adults are randomly selected the probability that exactly 2 of them do not require a vision correction is _________.

A recent study has shown that 68% of parents allow their children to ride their bicycles without using a helmet. If we randomly select 25 parents, what is the probability that exactly 18 of the parents allow their children to ride their bicycles without using a helmet? Compute your solution as a decimal and round your final answer to four decimal places. P(exactly 18) = __________
A researcher is interested in the reaction time of college students under high cognitive load. The students are asked to remember a random number sequence. While trying to remember the number sequence, the students are instructed to press the space key after they hear a tone on the computer. The researcher measures the time between when the tone occurs and when the space key is pressed. The variable being measured is a ___________ variable.
