Dr. Clifford Jones claims that the mean weight of bumblebee bats is 1.8 grams. We are interested in whether it's less than he claims. Using the t-distribution technique, answer the following questions.

Assuming that Dr. Clifford is correct, estimate the probability of a sample of 15 bumblebee bats producing an average as low as the one from our sample (one-sided p-value):

1.The degrees of freedom are df =______.

2.The test-statistic t = (positive version of t, three places after decimal) =______.

3.The p-value is between______(smaller) and ______ (larger, exact answers).
