Question

Fertilizer: A new type of fertilizer is being tested on a plot of land in an orange grove, to see whether it increases the amount of fruit produced. The mean number of pounds of fruit on this plot of land with the old fertilizer was pounds. Agriculture scientists believe that the new fertilizer may change the yield. State the appropriate null and alternate hypotheses.

Answer 1

Explanation:

The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.

The alternative hypothesis what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.

From the given situation,

The mean number of pounds of fruit on this plot of land with the old fertilizer was 416 pounds. This is the null hypothesis.

H0 : µ = 416

Agriculture scientists believe that the new fertilizer may decrease the yield. This is the alternative hypothesis.

H0 : µ < 416
