For each of the following parts, calculate their p-values.

1. In testing the following hypotheses:

H₀: = 0

H_A:> 0

A sample of size 30 were taken from a population whose variance was unknown. The value of the test statistic was calculated to be t = 1.843.

2. In testing the following hypotheses:

H₀: p = 0

H_A: p 0

by taking a simple random sample with the value of test statistic being z = 0.79.
