1 7/11 = 18/11
2 5/6 = 17/6
Product = 18/11 * 17/6
= 306 / 66 = 51/11 = 4 7/11 Answer
Answer: B

Answer:
the unknown side of triangle is 15 in :)
Using the normal distribution, it is found that the percentage of people spend <u>between 41 and 56 minutes</u> watching TV shows on this streaming service is:
a) 13.5%
In a normal distribution with mean
and standard deviation
, the z-score of a measure X is given by:
- It 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, which is the percentile of X.
In this problem:
- The mean is of 71, hence

- The standard deviation is of 15, hence

The proportion <u>between 41 and 56 minutes</u> is the <u>p-value of Z when X = 56 subtracted by the p-value of Z when X = 41</u>, hence:
X = 56:



has a p-value of 0.16
X = 41:



has a p-value of 0.025
0.16 - 0.025 = 0.135
0.135 x 100% = 13.5%
Hence option a is correct.
