The first exam grades of last semester's Stats class had a mean of 67 with a standard deviation of 5 points. Answer the following questions:

1. Jenny received a score of 80. What is her z-score? Is it positive or negative? Why?
2. Michael's z-score was a -1.5. Did he do better or worse than the average? How can you tell? And by how many points?
3. Anne's z-score was a 0. What does this tell you about her score in relation to the mean?
4. John received a score of 65. What is his z-score? Is it positive or negative? Why?

For the students in the first part of this question (Jenny, Michael, Anne, and John):

e. Which (if any) students fall into the middle 68% of the distribution?

f. Which (if any) students fall outside of the middle 68% of the distribution?

g. Which (if any) students fall into the top 5% of the distribution?

h. Which (if any) students fall into the bottom 5% of the distribution?

Software: For the following data:

x={5,3,2,3,6,5,5,4,4,5,4,5,4,5,5,5,5,4}

1. Using Software find the Mean, Median, Mode and Standard Deviation. Paste your output:
2. Construct a frequency histogram:
3. Describe the distribution (modes, skew, etc) and indicate how the relationship between the mean and median also reflects the observation you have made.
4. Using software, convert each score in this distribution into a z-score. Then construct a frequency histogram of the z-scores
5. Describe the similarities between the raw-score histogram you created and the z-score histogram. What are the differences, if there are any?

For the following set of January 2014 temperature (in Fahrenheit) data:

x = {32, 18, 55, 68, 48, 7, 40, 34}

Find the mean, median, mode, range, standard deviation, and variance in SPSS/JAMOVI. Paste below ONE table which contains all of the above statistics. Indicate the steps you took to construct this table.
