Answer: 14000
Step-by-step explanation:
From the question, the first thing is to first calculate the simple interest (S.I). This will be:
S.I = (principal × rate × time)/100
where principal = 10,000
rate = 4%
time = 10 years
Simple interest = (10,000 × 4 × 10)/100
= 400000/100
= 4000
The total value after 10 years will be th addition of the amount invested and the interest. This will be:
= 10,000 + 4000
= 14000
Answer: (0.994, 0.998)
Step-by-step explanation:
Given : Sample size : n= 25 < 30 , so we use t-test.

Critical t-value use for 98% confidence :

Formula to find the confidence interval :-

i.e. 

Hence, the required confidence interval : (0.994, 0.998)
