An agronomist hopes that a new fertilizer she has developed will enable grape growers to increase the yield of each grapevine by
Phoenix [80]

Answer:

Yes. Fertilization increases grape yields by more than 5 pounds.

Step-by-step explanation:

Let f-fertilized and o-old(unfertilized)

#First, we use our data to calculate the standard error:

SE(\bar y_f-\bar y_o)=\sqrt{\frac{s_f^2}{n_f}+\frac{s_o^2}{n_o}}\\\\=\sqrt{\frac{3.7^2}{44}+\frac{3.4^2}{47}}\\\\=0.7464

#State both null and alternative hypothesis:

H_o:\mu_f-\mu_o=0\\\\H_A=\mu_f-\mu_o>0

#We determine our degrees of freedom as 87.02(using R), we now compute the t-value as:

t=\frac{\bar y_f-\bar y_o}{\sqrt{\frac{s_f^2}{n_f}+\frac{s_o^2}{n_o}}}\\\\\\t=\frac{53.4-52.1}{\sqrt{\frac{s_f^2}{n_f}+\frac{s_o^2}{n_o}}}\\\\\\t=\frac{1.3}{0.7464}\\\\t=1.7417\\\\P=P(t_{87.0>1.7417}=1-0.9575=0.0.0425

Since, the p-value is low, we Reject the null hypothesis. The is enough evidence suggesting that grape yields increase by more than 5 pounds than mean yields of  unfertilized grapes.

What is 243.875 rounded to the nearest tenth
Kay [80]

Note that the tenth place value is 8 (bolded):

243.875

Look at the place value directly right of the bolded number (hundredth place value). It is a 7. Because 7 is greater than 5, round up

243.875 rounded to the nearest tenth = 243.9

243.9 is your answer

hope this helps
