1) You did a two-tailed t test for means equality and in step #2 you got a t value of 2.333. Assuming 22 degrees of freedom, calculate the exact step #5 p-value.

2) A new vaccine for Ebola has entered clinical trials. Preliminary results are good but it seems that 5% of treated patients develop the side effect of rashes on their bodies.

a) If 112 people received this vaccine, what is the probability that 5 or more of these people develop the side effects of rashes? Use the normal approximation to a binomial without the continuity correction.

b) If 112 people received this vaccine, what is the probability that two or less people develop the side effects of rashes? Use the normal approximation to a binomial without the continuity correction.
