Answer:
0.61196
Step-by-step explanation:
When we are given a random number of samples , we solve using the z score formula
z = (x-μ)/σ/√n
where x is the raw score
μ is the population mean = 34.6
σ is the population standard deviation = 13.6
n is the random number of samples = 37
For x = 32
z = 32 - 34.6/13.6/√37
z = -1.16288
Probability value from Z-Table:
P(x = 32) = 0.12244
For x = 36
z = 36 - 34.6/13.6/√37
z = 0.62617
Probability value from Z-Table:
P(x = 36) = 0.7344
The probability their mean hours worked per week is between 32 and 36 hours per week is calculated as:
P(x = 36) - P(x = 32)
= 0.7344 - 0.12244
= 0.61196
19.
To find this you first have to find the f(x) values for x = 5 and x = 8
x = 5
f(x) = 5^2 + 6(5) + 11
f(x) = 25 + 30 + 11
f(x) = 66
x = 8
f(x) = 8^2 + 6(8) + 11
f(x) = 64 + 48 + 11
f(x) = 123
Then you subtract the two from each other to see how much it has changed in those 3 numbers.
123 - 66 = 57.
Then you take that answer and divide it by the change in x (which is 3)
57/3 = 19
