A normal distribution has a mean of 50 and a standard deviation of 4 . a. Compute the probability of a value between 44.0 and 55.0. (Round intermediate calculations to 2 decimal places and final answer to 4 decimal places.) b. Compute the probability of a value greater than 55.0. (Round intermediate calculations to 2 decimal places and final answer to 4 decimal places.) c. Compute the probability of a value between 52.0 and 55.0. (Round intermediate calculations to 2 decimal nlaces and final answer to 4 decimal A normal distribution has a mean of 50 and a standard deviation of 4. Determine the value below which 95% of the observations will occur. (Round z value and final answer to 2 decimal places.)
