Answer:

(26.6,29.4)

Step-by-step explanation:

The 98% confidence interval can be computed as

Point estimate± Margin of error

Point estimate=mean number of hours watching TV by college students=28.

Margin of error=1.4.

The 98% confidence interval for mean number of hours watching TV per week for all college students

28± 1.4

(28-1.4,28+1.4)

(26.6,29.4).

SOVA2 [1]

The simple interest Trey earns if he makes no additional deposit or withdrawal for a period of 6 years is 600

<h3>How to calculate simple interest?</h3>

  • Principal = 5,000

  • Rate = 2%

= 2/100

= 0.02

  • Time = 6 years

Simple interest = principal × rate × time

= 5000 × 0.02 × 6

= 600

Therefore, the simple interest Trey earns if he makes no additional deposit or withdrawal for a period of 6 years is 600
