x ≥ 9
Answer:
12 minuts
Step-by-step explanation
If you divide 95 by ten you get 9.5, and 9.5 to 95 and you get 104.5 and it is 11 minuts. add it again and you are at 114 words and it is 12 minuts.
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
