Amanufacturer claims that 40% of households are planning to purchase a new television in the next two years. an investment analyst is skeptical of this claim. in a survey of 1,010 randomly selected american households, only 374 responded that they plan to purchase a tv in the next two years. is there convincing evidence that less than 40% of u. s. households plan to purchase a tv? what are the appropriate hypotheses for this test?

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: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
