Historically, a Certain Region Has Experienced 65 Thunder Days Annually $\alpha = 0.01$

question 111

Multiple Choice

Historically, a certain region has experienced 65 thunder days annually. (A "thunder day" is day on which at least one instance of thunder is audible to a normal human ear) . Over the past eleven years, the mean number of thunder days is 55 with a standard deviation of 20. Can you conclude that the mean number of thunder days is less than 65 ? Use the $\alpha = 0.01$ level of significance.

• A) There is not enough information to draw a conclusion.
• B) Yes. The number of thunder days appears to be less than 65.
• C) No. There is insufficient evidence to conclude that the number of thunder days is less than 65.
