Using the <u>normal distribution and the central limit theorem</u>, it is found that there is an approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.
Normal Probability Distribution
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.
- By the Central Limit Theorem, for n instances of a normal variable, the mean is
while the standard deviation is
.
In this problem:
- Mean of 4 candies, hence
. - Standard deviation of 1.5 candies, hence
. - She visited 35 houses, hence

The probability is the <u>p-value of Z when X = 122</u>, hence:

By the Central Limit Theorem



has a p-value of 0.
Approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.

Answer:
<em>B) Victor</em>
Step-by-step explanation:
<em>A positive value for r implies a positive linear correlation, while a negative value for r implies a negative linear correlation. The
</em>
<em>closer |r| is to 1, the stronger the correlation, and the stronger the correlation, the more reasonable the data model. Since |–0.91| =
</em>
<em>0.91, |0.73| = 0.73, |–0.44| = 0.44, and |0.88| = 0.88, the person with the most reasonable model for his or her data is</em><em> B) Victor!</em>
