Nationally, about 11% of the total U.S. wheat crop is destroyed each year by hail.+ An Insurance company is studying wheat hall damage claims in a county in Colorado. A random sample of 16 claims in the county reported the percentage of their wheat lost to hall. 14 7 10 10 12 21 12 13 9 11 23 19 15 8 11 6 The sample mean is x = 12.6%. Let x be a random variable that represents the percentage of wheat crop in that county lost to hall. Assume that x has a normal distribution and o = 5.0%. Do these data Indicate that the percentage of wheat crop lost to hall in that county is different (either way) from the national mean of 11%? Use a = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. Will you use a left-talled, right-tailed, or two-tailed test? O Ho: H = 11%; Hj: # # 11%; two-tailed O Ho: H = 11%; H1: H > 11%; right-tailed O Ho: M # 11%; H1: H = 11%; two-tailed O Ho: M = 11%; H1: M
