The average production of peanuts in Virginia is 3000 pounds per acre. A new plant foodhas been developed and is tested on 60 individual plots of land. The mean yield with thenew plant food is 3120 pounds of peanuts per acre, and the population standard deviationis 578 pounds. At a = 0.1, can you conclude that the average production has increased?Source: The Old Farmer's Almanac.a. State the hypothesis and identify the claim.Ho:μ 3000 and H₁:µ ■ 3000b. Find the critical value(s) from the appropriate table.Since α = 0.1 and the test is atailed test, the critical valueis z =c. Compute the test value.Z =x-μo/√nd. Make the decision to reject or not reject the null hypothesis.Since the test valueis inside/ outside the critical region, thedecision is to reject/ not reject the null hypothesis.e. Summarize the results.There is enough/ not enough evidence to support the claim that the averageproduction of peanuts has increased.
