STAT 1127-Compute the mean and standard deviation for the

. Compute the mean and standard deviation for the July 2006 maximum temperature data. How many daily records were set that month?

2. Compute the mean and standard deviation for the July 1986 maximum temperature data. Compare with the values from 2006.

3. Suppose there has been no change to the environment and the July maximum temperature in Chadron, NE typically has the mean and standard deviation you computed for 1986. Use Chebyshev’s Theorem to discuss how likely it would be to achieve a temperature of 111 ^oF as was observed in 2006.

4. Using the data from the current Pollstar chart, suppose the act at the top of the chart has had 26,902 requests. Approximately how many requests has the band in fourth place received.

6. Which corporations cereals exhibit the widest range in their rating? Ignore the data for American Home Food products as there is only one data point.

7. Compute the 5-number summary for the ratings of Kellogg brand cereal noting any outliers.

8. The harmonic and geometric means discussed in your text are significantly different from the usual arithmetic mean or average. One place the harmonic mean arises is in computing average speeds. Surprisingly. the geometric mean arises in the computations that determine the number of seats a state gets in the House of Representatives. Use your favorite search engine to learn more about this use of the geometric mean and write a brief summary of the computation.
