Question

Over the last century (100 years), there were 100 months of September. Each month

of September had 30 days. For a study of climates, 200 days in September during the

past century are selected at random and the high temperature for the day is recorded

in the city of Ukiah. For these days, M = 81. 9 Fahrenheit, s = 7. 4 Fahrenheit. The

lowest temperature was 52 F and the highest was 107 F.

Your job is to describe the above situation one sentence at a time. Use each of the

following terms in a separate sentence to say something about the above situation.

Please write complete sentences. You should have a total of eight sentences, 2

points each.

1. Population

2. Sample

3. Measures of Central Tendency

4. Measures of Variability

5. Mean

6. Range

7. Standard Deviation

8. Variance

Answer 1

Step-by-step explanation:

The population in question consists of the high temperatures recorded in the city of Ukiah during 200 randomly selected days in September over the past century.

The sample size is 200 days in September with their respective high temperatures recorded in Ukiah over the past century.

The measures of central tendency for the sample are M = 81.9 Fahrenheit, which represents the mean high temperature for the 200 days.

The measures of variability for the sample include the range of temperatures recorded, from the lowest of 52 F to the highest of 107 F.

The mean high temperature for the 200 days is M = 81.9 Fahrenheit.

The range of high temperatures recorded in the sample is from the lowest of 52 F to the highest of 107 F.

The standard deviation for the sample is s = 7.4 Fahrenheit, which indicates the degree of variability of the high temperatures around the mean of 81.9 Fahrenheit.

The variance for the sample is s^2 = 54.76 Fahrenheit^2, which is the square of the standard deviation and measures the spread of the high temperatures from the mean.
