The third one is the answer
The critical values are fixed values which can be
obtained from the standard t crit
tables. We can find the critical value tc when the degrees of freedom
and confidence level are given. The degrees of freedom is simply:
Degrees of Freedom = Number of samples – 1
Degrees of Freedom = 19 – 1
Degrees of Freedom = 18
From the t critical tables, the tc corresponding to Degrees
of Freedom equal to 18 and Confidence level equal to 95% is as follows:
tc = 2.101
Therefore this means that any t value beyond 2.101, we already
reject the null hypothesis.

The number would be 15 baskets because each person sharing the picnic basket together would each get 1 sandwich and 1 granola bar.
