The number of semester hours of college credit taken by first-time candidates for a certain professional exam has a Normal distribution with a mean of 120 hours and a standard deviation of 16 hours. Consider a random sample of n first-time candidates for the exam and let x represent the mean number of hours of college credit taken for the sample. Complete parts a through e below. Click the icon to view the table of normal curve areas. ..... a. Describe the shape of the sampling distribution of x. A. The shape is Normal distribution only when sample size is greater than 30 B. The shape is Normal distribution for any sample size O C. is always the same as the distribution of the population D. The shape is skewed right b.

An experiment was performed to determine whether different types of chocolate take different amounts of time to dissolve. Forty people were divided into five groups. Each group was assigned a certain type of chocolate. Each person dissolved one piece of chocolate, and the dissolve time (in seconds) was recorded. For comparison, each person in each group also dissolved one piece of butterscotch candy; these pieces were identical for all groups. The data, which include the group, the dissolve times for both chocolate and butterscotch, the difference between the dissolve times, and the ratio of the dissolve times, are presented in the following table. Note that the design is slightly unbalanced; group 3 has nine people and group 5 has only seven.

The accompanying data are 45 commute times to work in minutes for workers of age 16 or older in Chicago. Construct a frequency distribution. Use a class width of 15 minutes and begin with a lower class limit of 0 minutes. Do the data amounts appear to have a normal distribution? Examine the data and identify anything appearing to be unique. Click the icon to view the commute times. Frequency Time (minutes) 0-14 4 15-29 15 30-44 11 45-59 9 60-74 75-89 5 1 (Type whole numbers.) Do the data amounts appear to have a normal distribution? OA. No, because while the distribution is approximately symmetric, the frequencies start at a maximum and become low. B. No, because while the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, the distribution is not symmetric. OC. Yes, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximately symmetric. OD. No, because the…
