Barry, an analyst, found that his research results were all normally distributed.He converted the results to Z-scores and needed assistance to find the probabilities for the following.

1. Find P (Z < 1.3)(1 Mark)
2. Find P (Z > -1.03)(2 Mark)
3. Find P (-1.10 < Z < 1.58)(2 Marks)

Barry's assistant, Tom, had a different problem; he had probabilities that he needed help to convert to Z-scores.

1. The probability is 0.56 that Z is less than what number?(1Mark)
2. The probability is 0.35 that Z is greater than what number?(2Marks)
