Click the icon to view the standard normal distribution table.
Thus, the final answer is
Step 1 :Let
Step 2 :The standard normal distribution table gives the probability that a standard normal random variable is less than a given value. In other words, it gives the cumulative distribution function (CDF) for a standard normal random variable.
Step 3 :To find
Step 4 :The CDF at 0 is 0.5 (since the standard normal distribution is symmetric about 0), and the CDF at -1.74 can be found from the table.
Step 5 :Using the given values, we have cdf_0 = 0.5 and cdf_minus_174 = 0.0409.
Step 6 :Subtracting these values, we get p = 0.4591.
Step 7 :Thus, the final answer is
