Answer: 0.022
Explanation:
Let p be the population proportion of horses were fed mostly alfalfa.
We are given that :
, since alternative hypothesis (
) is right tailed , so the test is a right-tailed test.
Also, we have
Sample size= 62
Sample proportion=

Test statistic for population proportion:-

Substitute all values ,

P-value for right tailed test :
P(z>2.01)=1-P(z<2.01) [∵P(Z>z=1-P(Z<z))]
=1-0.9777844 [By using z-value table]
=0.0222156≈0.022
Hence, the P-value for this test is 0.022 .
