A random sample of 108 customers was taken in a shopping mall. The mean number of items purchased by the customers in the sample was 3.9 with a standard deviation of 1. The median was 4.4, and the mode was 4. A graph shows that the distribution of the data is highly skewed to the left. A store manager wants to calculate the probability that a customer will purchase at least 4 items. Which statement is true?

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

your answer   is c
