a . The test statistic is -1.160740861

b. The p value is 0.2457473

Let the point estimate be 'a'. The formula for test statistic is:

Z = (a - p) / √ { [ p×(1-p) ]÷n }

Point Estimate 'a' = 30/78 = 0.384615385

Z = (0.384615385 -0.45 ) / √[ (0.45 × 0.55) ] / 78

Z = -0.065384615 / 0.056330071

Z = -1.160740861

Suppose a​ 40-year-old person deposits ​$12 comma 00012,000 per year in an Individual Retirement Account until age 65. Find the
tatiyna

Answer:  interest earned = $8942372340

$8942672340 this is amount after 25 years.

Explanation:

formula used:    S= R*[ (1+<em>i </em>)ⁿ-1 / <em>i </em>]

where:

S is future value

R is periodic payment

<em>i </em> is interest rate period

n is number of periods

R= $3000

n= 65-40=25   now 25*4=100   QUARTERLY that is why we used 4

<em>i </em>= 55% which is equal to 0.55

so, for quarterly <em>i= </em>0.55/4= 0.138

now putting them in formula given above

S= 3000*[ (1+0.138)¹⁰⁰-1] / 0.138

S= $8942672340 (future value )

total money deposited = number of period * periodic amount

                                        = $3000*100 = $300,000

interest earned = future value - total money deposited

                           = 8942672340 - 300,000

 interest earned = $8942372340

Which of these statements is false? A company comparison should not be made with industry averages if the company does not clear
ValentinkaMS [17]

Answer:

A company comparison should not be made with industry averages if the company does not clearly fit into any one industry.

Explanation:

In Business management, it is important to note that many companies will not clearly fit into any one industry.

Hence, when using industry averages, it is often necessary to use an industry that the firm best fits rather than randomly picking up any industry. Additionally, the analysis of an organization's financial statements would be more meaningful if the results are compared with industry averages and with results of competitors.

Any financial service sought after, should use its best judgment by analyzing and identifying which industry the firm best fits.
