Answer:
(a) The z-critical value for a left-tailed test, for a significance level of α=0.05 is -1.64.
(b) Since -1.54 > -1.64, therefore we accept H₀.
Step-by-step explanation:
(a)
It is given that the value of test statistic is
We need to test the claim that p<0.18.
Null hypothesis:
Alternative hypothesis:
It is a left tailed test.
Significance level:
The z-critical value for a left-tailed test, for a significance level of α=0.05 is -1.64.
(b)
It is a left tailed test and critical value is -1.64 it means the region on left of -1.64 is rejection region.
The value of z is -1.54 and the critical value is -1.64.
We know that -1.54 > -1.64.
Therefore we accept H₀.
The answer is A...

Answer:
#3
Step-by-step explanation:
from the formula given, the part "(1.025)" would be the growth factor or rate.
This part has a formula:
(1 + r)
where r is rate
So substituting, we get:
So, in pecentage, we have to multiply, thus we get:
0.025 * 100 = 2.5%
