In Juneau, Alaska, the 30-year annual snowfall average is 86.7 inches with a standard deviation of 40.4 inches. The last four years saw an average annual snowfall of 115.7 inches, 62.9 inches, 168.5 inches, and 135.7 inches.

Which of the following is a conclusion that she may make? The z-statistic is 1.44, so the null hypothesis cannot be rejected.
