A Math study group consists of 6 people. The following scores represent their IQs: 92, 104, 104, 106, 108, and 110. a)

A student is interested in examining how intelligent this group is. Are the data treated as a sample or population?

b) Calculate the mean and standard deviation for this group

Debbie took a History exam and an English exam. The following table shows her score as compared to the class mean for each subject

Here are the weights of 20 men before participating in a weight-loss trial.

157 176 179 183 170 184 182 170 160 180

181 169 188 162 155 171 197 170 150 188

a) Are these data discrete or continuous?

b) Construct a frequency distribution to display these data. Use 5 classes.

c) Construct a Histogram based on the frequency distribution.

A survey was given to a class of 20 students asking them to rate the quality of their instructor at the end of a course. Here is a list of their responses:

Excellent Excellent Average Poor Above Average

Poor Above Average Average Excellent Excellent

Average Above Average Above Average Excellent Average

Above Average Blew Average Excellent Above Average Below Average

a) Are these data nominal or ordinal?

b) Construct a qualitative frequency distribution based on these data showing the frequency and the relative frequency for each class.

Please use typing to explain how to do them to me and not a picture
