Assume that the population of heights of treated plants is, Ask an Expert

Statistics

Heights were measured for a random sample of plants grown while being treated with a particular nutrient. The sample mean and sample standard deviation of those height measurements were centimeters and centimeters, respectively.

Assume that the population of heights of treated plants is normally distributed with mean . Based on the sample, can it be concluded that is different from centimeters? Use the level of significance.

Perform a two-tailed test. Then fill in the table below.

Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
