Answer:
69.15% probability that a randomly selected customer spends less than $105 at this store
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What is the probability that a randomly selected customer spends less than $105 at this store?
This is the pvalue of Z when X = 105. So



has a pvalue of 0.6915
69.15% probability that a randomly selected customer spends less than $105 at this store
Answer: I would say B would be the answer Because....
Step-by-step explanation:
if about 20 to 23 cars pass through every 26 minutes, and haw many cars pass by in 156 minutes...
26 x 6 = 156
6 x 20 = 120
6 x 21 = 126
6 x 22 = 132
6x 23 = 138
all thoes numbers are around B.
