5.) Suppose a researcher collected data on the mean height of tomato plants grown in organic soil, and in computing the confidence interval for the population mean, and the margin of error was computed to be 4.86 inches.

Use that to answer the following questions:

a. What is the length of the confidence interval (i.e. from the first number to the second how long is the interval) if the margin of error is 4.86 inches? (2pts)

b. If the data collected came from 25 tomato plants and the mean for the sample was 13.8 inches what is the confidence interval that was found? (2pts)

c. Suppose the sample size was increased from 25 plants to 100 plants, how would the margin of error change? Be specific. (2pts)
