Answer:
μ > 21.21
Test statistic = 1.217
Kindly check explanation for more details
Step-by-step explanation:
The null hypothesis, H0 : μ = 21.21
Alternative hypothesis, H1 : μ > 21.21
The test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(21.212 - 21.21) ÷ (0.01 / √2)
= 1.217
The critical value :
From the t distribution :, one tailed = 2.434
Decision region :
Reject H0 if test statistic > critical value
1.217 < 2.434 ; We fail to reject the null ` ; and conclude that there is not enough evidence to support the claim.
In order to solve this problem, the first thing we are going to do is find out how much is 9% of 1000, since 9% is the interest per year. So 0.09 x 1000 and that would be 90. And since the interest earned is added to the account, the account will now have a total of $1090 which is now the new principal. Based on this new principal, we need to know the 9% of it again to know how much interest in earned in the following year. So that would be 0.09 x 1090 and the result is $98.10. Hope this answer helps.
