Determine the area under the standard normal curve that lies to the left of (a) Z = 1.02, (b) Z = -0.72, (c) Z = 1.33, and (d) Z = 0.95

(a) The area to the left of Z = 1.02 is .

This subject is Statistics not Mathematics my bad sorry

(a) The area to the left of Z = 1.02 is 0.8461

(b) The area to the left of Z = -0.72 is 0.2358

(c) The area to the left of Z = 1.33 is 0.9082

(d) The area to the left of Z = 0.95 is 0.8289

Step-by-step explanation:

The z score is a measurement used in statistics to determine the relationship between a value and the mean (average) of a group of values, measured from the standard deviations.

The z score table shows the area in percentage to the left of a given z score in a normal distribution.

From the z score table of the normal distribution:

(a) The area to the left of Z = 1.02 is 0.8461 = 84.61%

(b) The area to the left of Z = -0.72 is 0.2358 = 23.58%

(c) The area to the left of Z = 1.33 is 0.9082 = 90.82%

(d) The area to the left of Z = 0.95 is 0.8289 = 82.89%

4 + 5 7/9= 9 7/9
