The U. S. Department of Transportation provides estimated number of miles that residents of large metropolitan areas travel per day in a car. In a random sample of 50 City A residents the mean was 22 miles with a standard deviation of 4 miles, and in a random sample of 50 City B residents the mean was 28 miles with a standard deviation of 8 miles. You want to know if the mean difference in number of miles travelled per day between City A and City B is different from zero in the population. a. One sample t test
b. Paired samples t test
c. Independent samples t test
d. One-way analysis of variance (ANOVA)

c. Independent samples t test

Explanation:

An independent samples t test is used in the above case. Independent samples t test are employed when comparison is between two independently groups. Independent samples t test compares the mean of two independent groups as in above to determine if there is a statistically significant difference between them for the purpose of making a decision. For example in the above scenario if there is a difference in the means, we can conclude that City A and city B residents do not travel same distance in miles

b. a single paragraph.

a paragraph is a series of sentences that are organized and make sense, and are all related to a single topic . almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. this is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus the reader see the organization of the essay into subjects in order to be able to understand its main points.
