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
Answer:
21x²
Step-by-step explanation:
hopefully A is a typo
I believe the answer is 18, because 5x3=15, so we can only assume that N is 6x3=18.
Answer:
8.91
Step-by-step explanation:
Given: 0.95 = log x,
we can conclude that:
0.95 log x
10 = 10
0.95
which in turn is equivalent to x = 10 whose value is 8.91
C=P[(1+r)^n-1]
C = COMPOUND INTEREST
P = PRINCIPAL
r = rate per period
n = number of periods
