[3](10) Suppose that 65% of all registered voters in a certain area favor a 7-day waiting period prior to purchase of a handgun. Among 225 randomly selected voters, what is the probability that fewer than 125 favor such a waiting period: (a) using a binomial distribution? ibj using a normal approximation if applicable? [4](8) Men's heights are normally distributed with mean 69.0 in. and standard deviation 2.8 in. Tall Clubs International is a social organization for tall people. It has a requirement that men must be at least 76 in. tall. a) What percentage of men meet that requirement? b) If the requirements are changed so that the tallest 5% of men are eligible, what is the new height for ment [5](5) The normal quantile plot shown to the right represents duration times (in seconds) of eruptions of a certain geyser from the accompanying data set. Examine the normal quantile plot and determine whether it depicts sample data from a population with a normal distribution. Choose the correct answer below. 3.00- 2 00- A. The distribution is not normal. The points are not 1.00- reasonably close to a straight line. 0.00- B. The distribution is not normal. The points do not show any systematic pattern. -1.00- C. The distribution is normal. The points show a sys- -2.00- tematic pattern that is not a straight-line pattern. -3.00- D. The distribution is normal. The points are reason- 100 150 200 250 300 ably close to a straight line and do not show a sys- X Value tematic pattern that is not a straight-line pattern
