Answer:
There is convincing evidence that less than 40% of US households plan to purchase television in the next two years.
Null hypothesis H•= 40%
Alternative Hypothesis Hi < 40%
Step-by-step explanation:
Null hypothesis H•= 40%
From the survey, percentage of household that responded that they plan to buy new television in the next two years is given by
= 374/1010 × 100%
= 37%
Therefore,
Alternative Hypothesis Hi<40%
Hence, there is convincing evidence that less than 40% of US households plan to purchase television in the next two years. Since both null and alternative Hypothesis are less than or equal to 40%.
Answer:
Step-by-step explanation:
If you travel at 8 miles per hour, where t is the number of hours, then, using the formula (r being the rate, in this case 8), the equation becomes .
Hope this helped!
answer is 2720
solution below
First, converting R percent to r a decimal
r = R/100 = 4.5%/100 = 0.045 per year.
solving our equation:
A = 2000(1 + (0.045 × 8)) = 2720
A = $2,720.00
the total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 4.5% per year for 8 years is $2,720.00
