Your first t-test

Now you will perform your first statistical test! We want to compare the mean heights in cm of the Sample_A group with a given value. We want to see whether the mean weight of the people in this sample is significantly different from the chosen cut-off point of 65 kg. You'll use a one-sample t-test, which allows you to compare the mean of a sample with a chosen value. You'll perform this test on the sample provided versus the crucial value of 65 kg, and test its significance by comparing the value of alpha to the p-value. scipy.stats has been loaded into the workspace as stats.

Perform a one-sample t-test comparing the mean of Sample_A to 65; assign the output to t_result and print it.
Using a standard alpha value of 0.05, test the statistical significance of the result by comparing the p-value to alpha and print the appropriate message.
