For a certain brand of tomato seeds, the seed package claims that it takes 87 days after planting for the tomato plants to produ
nexus9112 [7]

Answer:

D. Sarah does not have convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.

Step-by-step explanation:

The population mean, μ is given as 87

This population value is used to state the Null hypothesis ;

H0 : μ = 87

The alternative hypothesis is the opposite of the Null ; and hence, claims that the mean is different from the population mean, μ ≠ 87

H1: μ ≠ 87

The Decison level :

When Pvalue < α ; We reject the Null otherwise we fail to reject the null

The given p and α value :

P-value = 0.0752

α = 0.05

0.075 > 0.05 ; Hence ;

Pvalue > α ; We fail to reject the Null

We can thus conclude that there is not enough evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.
