Answer:
The probability that their mean life will be longer than 13 years = .9943 or 99.43%
Step-by-step explanation:
Given -
Mean
= 15 years
Standard deviation
= 3.7 years
Sample size ( n ) =22
Let
be the mean life of manufacturing items
the probability that their mean life will be longer than 13 years =
=

= 
=
Using Z table
= 1 - .0057
= .9943

Step-by-step explanation:
Intercept form of a line : Y = mx + b
m = y2 - y2 / x2 - x1 ....use this to find the slope whenever 2 points are given.
In this case it's directly given.
Answer:
if this is on the graph it would be the slope or it would be (m) due to it being in m's spot y = m x + b
