A variable of a population has a mean of u = 300 and a standard deviation of o = 35.a. The sampling distribution of the sample mean for samples of size 49 is approximately normally distributed with meanand standard deviationb. For part (a) to be true, what assumption did you make about the distribution of the variable under consideration?O A. No assumption was made.B. Uniform distribution.O C. Normal distribution.C. Is the statement in part (a) still true if the sample size is 16 instead of 49? Why or why not?O A. Yes, the sampling distribution of the sample mean is always normal.O B. No. Because the distribution of the variable under consideration is not specified, a sample size of at least 30 is needed for part (a) to be true.O C. No, the sampling distribution of the sample mean is never normal for sample size less than 30.

B Choosing a topic Sk.. For data that is not normally distributed we can't use z-scores. However, there is an equation that works on any distribution. It's called Chebyshev's formula. The formula 1 where p is the minimum percentage of scores that fall within k k2 is p = 1 - standard deviations on both sides of the mean. Use this formula to answer the following questions. a) If you have scores and you don't know if they are normally distributed, find the minimum percentage of scores that fall within 2.2 standard deviations on both sides of the mean? b) If you have scores that are normally distributed, find the percentage of scores that fall within 2.2 standard deviations on both sides of the mean? c) If you have scores and you don't know if they are normally distributed, how many standard deviations on both sides of the mean do we need to go to have 64 percent of the scores? Note: To answer part c you will need to solve the equation for k.
