Determine the area under the standard normal curve that lies to the left of (a) Z=081. (b) Z=0.43. (c) Z= -0.33. and (d) Z= 1.04 .
1 answer:
Using the normal distribution , the areas to the left are given as follows:
a) 0.7910.
b) 0.6664.
c) 0.3707.
d) 0.8508.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X, and is also the area to the left of Z .
Hence:
The area to the left of Z = 0.81 is of 0.7910 . The area to the left of Z = 0.43 is of 0.6664 . The area to the left of Z = -0.33 is of 0.3707 . The area to the left of Z = 1.04 is of 0.8508 .

-4 and 0 are the x-intercepts
I drew up a (bad looking but still useful) grid and it proves the answer to be neither. even if the lines went continued in each direction it shouldn't be possible
