To check the accuracy of a particular weather forecaster, records were checked only for those days when the forecaster predicted rain "with 30% probability." A check of 25 of those days indicated that it rained on 10 of the 25.
a. If the forecaster is accurate, what is the appropriate value of p, the probability of rain on one of the 25 days?
b. What are the mean and standard deviation of x, the number of days on which it rained, assuming that the forecaster is accurate?
c. Calculate the z-score for the observed value, x=10. [HINT: Recall that z-score = (x-[math]\mu[/math])/[math]\sigma[/ math].]
d. Do these data disagree with the forecast of a "30% probability of rain"? Explain.
