After an extensive advertising campaign, the manager of a company wants to estimate the proportion of potential customers that r

ecognize a new product. She samples 120 potential consumers and finds that 54 recognize this product. She uses this sample information to obtain a 95% confidence interval that goes from 0.36 to 0.54.

Answer:

1. Referring to Problem , the manager wants to know the value of the population so the manager uses the sample to estimate the population proportion.

a. True

2. Referring to Problem , point estimate of the population proportion is = 0.45.

a. True

3. Referring to problem , the sample proportion is = 0.45.

b. False

4. Referring to Problem, the manager wants to know the value for the population so the manager uses the sample to estimate the population value

b. False

5. Referring to Problem , the parameter of interest is 54/120 = 0.45.

a. True

Explanation:

a) Data and Calculations:

Sample of potential consumers = 120

Proportion of the sample who recognize the product = 54

Confidence level = 95%

Confidence interval = 0.36 to 0.54

Point estimate = 54/120 = 0.45

b) A point estimate of a population parameter estimates the population parameter as a single value.  The point estimate of the sample mean, x, is also the point estimate of the population mean, μ.  To get the sample proportion, one needs to know the population value.  The sample value divided by the population value gives the sample proportion.

qaws [65]

Answer:

A. $115,291.30

B. $421,536.55

C. $1,471,502.67

Explanation:

The expression that describes the final amount of a $15,000 investment compounded annually for 35 years is:

A = \$15,000*(1+i)^{35}

A. 6% per year

i = 0.06

A = \$15,000*(1+0.06)^{35}\\A = \$115,291.30

B. 10% per year

i = 0.10

A = \$15,000*(1+0.10)^{35}\\A = \$421,536.55

C. 14% per year

i = 0.14

A = \$15,000*(1+0.14)^{35}\\A = \$1,471,502.67

Answer:

single-amount payment $925,160

Explanation:

Given data:

Amount $100,000

Rate 6%

interest semi annually 3%

Number of period 5

Lumpsum Payment = A\times {PVAF@ I,n}

                                = A\times {PVAF@ 3\%,5}

calculation for PVAF

PVAF @ I,N =\frac{(1-(1+I)^-N)}{I}

[email protected] 3%,5 = \frac{(1-(1+0.03)^{-5})}{0.03}

                          =4.58

                   

Lumpsum Payment =202000*4.58

                               =925160

7. Problems and Applications Q7 A dozen eggs cost $0.96 in December 2000 and $2.75 in December 2015. The average wage for worker
Novay_Z [31]

Answer:

By what percentage did the price of a dozen eggs rise?

  • [($2.75 - $0.96) / $0.96] x 100 = 186.46%

By what percentage did the wage rise?

  • [($21.26 - $14.28) / $14.28] x 100 = 48.88%

In order to earn enough to buy a dozen eggs, a worker had to work <u>4.04</u> minutes in December 2000 and <u>7.76</u> minutes in December 2015.

  • ($0.96 / $14.28) x 60 = 4.04 minutes
  • ($2.75 / $21.26) x 60 = 7.76 minutes

Workers' purchasing power in terms of eggs between 2000 and 2015.

  • purchasing power in terms of eggs in 2000 = 14.875 dozens of eggs per hour
  • purchasing power in terms of eggs in 2015 = 7.76 dozens of eggs per hour
