Question 15 Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find P63, the 63-percentile. This is the temperature reading separating the bottom 63% from the top 37%. P63 = C Submit Question

Question 23 A test had 12 items. A new version of a test was made by adding a set of 12 items which resembles the original 12-item test. The new test having 24-items was administered a group of students. The mean and the standard deviation of the new 24-item test scores were 18 and 6, respectively. The difference score between the original 12-item test and the new set of 12 items was calculated. The standard deviation of the difference scores was 3. Estimate reliability.

QUESTION 8 Nabisco claims that Chip Ahoy Cookies have an x ̅=28.67 chocolate chips per cookie with a SD=2.67. You randomly select 15 cookies from a new bag and carefully remove all the chocolate chips from each of the 36 cookies. You find the mean of the chocolate chips for the 15 cookies is 24.27 chocolate chips per cookie. Calculate the standard error for the chocolate chips in your experiment. (round to the nearest hundredth).

Question 1 (Spts) A random sample of 120 students at BAU was taken to estimate the participating to the office hours. Suppose that the population times have a normal distribution with a mean of 76 minutes and standartd deviation of 22 minutes. What is the standard error of the sample mean based on the given sample data? Use Excel to calculate it. Use two Decimals. Standard Error of the Mean:
Question 8 A survey found that women's heights are normally distributed with mean 64.2 inches and standard deviation 2.6 inches The survey also found that men's heights are normally distributed with mean 69.6 inches and standard deviation 3.4 inches Most of the live characters employed at an amusement park have height requirements of a minimum of 57 inches and a maximum of 64 inches 1. The percentage of men who meet the height requirement is _____ Circle which one is correct 2. Since most men (meet/do not meet) the height requirement, it is likely that most of the characters are (women/men) 3. The new height requirements are a minimum of______ inches and and maximum of _______inches
