Answer:
Yes
We fail to reject the alternative hypothesis Hₐ < 30, that is the average age of students is less than 30
Step-by-step explanation:
Yes because, there is an average age of a sample which can be tested against a null hypotheses
We put
Null hypothesis as H₀ = 30
The alternative hypothesis as Hₐ < 30
We have
With
= 29
μ = 30
σ = 5.2
n = 65
α = 10%
We have
Here we have z = -1.55 and critical z = -1.28
Which gives a critical of 29.83 with the probability P = 0.061 < 0.1 Hence we reject the null hypothesis as there is sufficient evidence to suggest that the average age is less than 30 years.
Answer:
15.84%
Step-by-step explanation:
There is no formula that will tell you the interest rate. It must be computed iteratively or found graphically. A financial calculator can do the work for you.
The parameters this one uses are
- number of payments (24)
- the amount financed (1925 -125 = 1800)
- the monthly payment, negative because it is being paid (-88.00)
- the remaining balance after all payments (0)
- the number of payments per year (monthly = 12)
- the number of times per year interest is compounded (monthly = 12)
