Perimeter
P = P1+P2
P1 = 4a P2=2(a+b)
P1=4*5 P2=2(3+5)
P1=20 P2=2*8
P2=16
P = 20+16
P=36
Area
A=A1+A2
A1= A2=a*b
A1= A2=3*5
A1=25 A2=15
A=25+15
A=40
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
