Answer:
Step-by-step explanation:
Given the mean is 3.2, standard deviation is 0.8 and the sample size is 64.
-We calculate the probability of a mean of 3.4 as follows:
#First determine the z-value:
#We then determine the corresponding probability on the z tables:
Hence, the probability of obtaining a sample mean this large or larger is 0.0228
h that happens. to me
Step-by-step explanation:
all the time
Step-by-step explanation:
first, add the whole numbers
6 + 7 = 13
then the fractions
3/8 + 5/6
we need to get common denominators
do you know how to do that
Step-by-step explanation:
2:3:5
2+3+5=10
2÷10 ×72=$14.4
3÷10×72=$21.6
5÷10×72=$36
Answer:
R = 6
Step-by-step explanation:
Remember... Circle area is:
A = pi×R^2
Where R is the circle radius.
Then,
Pi×R^2=36×Pi
R = square root of 36
R = 6
