Question

For a standard normal distribution, find:

P(-2.95 < z < 2.41)
Express the probability as a decimal rounded to 4 decimal places.

Answer 1

The probability between -2.95 and 2.41 is 0.99083.

Step-by-step explanation:

The probability can be found by finding the area under the standard normal curve between -2.95 and 2.41.

Using a Z-table, we can find these probabilities:

Z-score for -2.95: 0.0015

Z-score for 2.41: 0.99233

The probability between these two Z-scores is the difference between the two probabilities, which is:

0.99233 - 0.0015 = 0.99083
