Based on the national weather report, the temperature in California has a mean of 53 F with a standard deviation of 4.6 F. However, the Agriculture Weather Services claims that the mean temperature in California is more than that of the average of 53F based on the farmers' reports. In a random sample of 15 farmers, the mean temperature was 57.2 F. A right-tailed hypothesis test was conducted, which resulted in a 0.0371 p-value.
