I am working on statistics assignment and since statistics is not my primary field of studies I have difficulties with it. can someone please help me out?? I did stem and leaf display which I think looks OK but am not sure.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

The following data represent the weights (in kilograms) of a sample of 25 horses:

164 148 137 157 173 156 177 172 169 165

145 168 163 162 174 152 156 168 154 151

174 146 134 140 171

Use these data to answer the following questions:

a. Construct a stem-and-leaf display for the weights.

b. Find the median weight.

c. Compute the sample mean weight.

d. Compute the sample variance and sample standard deviation.

e. Construct a frequency distribution for the data, using five class intervals and the value 130 as the lower limit of the first class.

2. Relevant equations

it possible for the standard deviation of a data set to be larger than its variance? Explain.

3. The attempt at a solution
