1. Find P(z>-2.575). O 0.0050 O 0.6500 O 0.1950 O 0.9950

I believe the answer is 0.6500. I need a second opinion.

2. Find the probability of selecting a z score greater than -0.95.

O 0.5199 O 0.8289 O 0.1711 O 1.6450

I believe the answer is 0.5199. I need a second opinion.

3. Find z^ 0.05 O 0.4801 O 0.5199 O 1.645 O -1.645

I believe the answer is -1.64. I need a second opinion.
