Answer:
3.625
Step-by-step explanation:
Given a normal distribution :
Average weight = population mean = 172 pounds
Population standard deviation = 29 pounds
Number of samples selected(n) = 64
The standard deviation of the sample also called the standard error is the proportion of the population standard deviation to the square root of the number samples.
Sample standard deviation :
Population standard deviation /√n
= 29 /√64
= 29 / 8
= 3.625
Y = mx + b
Where m is the slope and b is the y-intercept
As you can already see it passes through the origin so b (the y-intercept) is (x, 0)
And the slope were it’s rise/run so it goes up 2.5 units and to the right 1 unit so it’s 2.5/1 = 2.5
m = 2.5
