Step-by-step explanation:
........................
I don’t know if this is right or not so, sorry if it’s wrong ;-;
1,2,3,4,5 = independent
c=1.25a = neither
$1.25, $2.50, $3.75, $5.00, $6.25 = dependent
Number of avocados = independent
Cost of avocados = dependent
If this is right then I’ll put the explanation in the comments, again sorry if it isn’t.
Using the normal distribution, it is found that 58.97% of students would be expected to score between 400 and 590.
<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.
The mean and the standard deviation are given, respectively, by:

The proportion of students between 400 and 590 is the <u>p-value of Z when X = 590 subtracted by the p-value of Z when X = 400</u>, hence:
X = 590:


Z = 0.76
Z = 0.76 has a p-value of 0.7764.
X = 400:


Z = -0.89
Z = -0.89 has a p-value of 0.1867.
0.7764 - 0.1867 = 0.5897 = 58.97%.
58.97% of students would be expected to score between 400 and 590.
