First off.. we need to get the units the same. All in hours,
or all in minutes. 36 minutes = 36/60 hours = 3/5 hours = 0.6 hours.
12 minutes = 12/60 hours = 1/5 hours = 0.2 hours
Set up a proportion:
0.2 is to 0.6 as x is to 22.5
x/22.5 = 0.2/0.6
x = 0.2(22.5)/0.6
x = 7.5 hours
thanx
heyaaaaa
Answer:
109.33
Step-by-step explanation:
given that the population has a distribution with a mean of 110 and a standard deviation of 8
Sample size n = 40
Std error of sample mean = std dev/square root of sample size
= 
From std normal distribution table we find that 30th percentile for Z is
-0.5244
Corresponding x score =
30th percentile = 109.33663
=109.33
