If x-10=15 and x=25
then the Hypothesis would be true.
25-10=15
the answer if those two are the answers it'd be A.
Answer:
150(1-x)
Step-by-step explanation:
120 is decreased by d%
Let x = d%
120 - 120*x
120(1-x)
Then it is increased by 25%
(120 (1-x)) +(120 (1-x))*.25
(120 (1-x)) +(30 (1-x))
150(1-x)

Answer:
real risk-free rate = 2.7 %
Step-by-step explanation:
Given data
Treasury bonds yield r = 5%
time = 5 year
(IP) = 1.9%
MRP = 0.4%
to find out
real risk-free rate r*
solution
we will find real risk-free rate r* by the given formula that is
Treasury bonds yield = real risk-free rate + IP + MRP + default risk premium + liquidity premium
so here default risk premium and liquidity premium both are zero
put all the other value we get real risk-free rate
real risk-free rate = 5% - 1.9 % - 0.4%
real risk-free rate = 2.7 %
Answer:
NO.
Step-by-step explanation:
From the question, we are given a random sample of 20 automotive batteries, a confidence interval =(0.22,0.33). Also, the population standard deviation is said to be less than 0.26 hour.
The confidence interval does NOT suggest that the variation in the batteries' reserve capacities is at an acceptable level.
REASON: If you look at the confidence interval, we can see that it contains the value for the standard deviation that is 0.26 and even MORE value than 0.26.
This does not give us any suggestion that the standard deviation is less than 0.26.
