Answer:

b. 0.055

Step-by-step explanation:

The point estimate of the proportion of people who wear hearing aids is

The number of people in the sample who wear hearing aids divided by the total number of people in the sample.

In this problem, we have that:

Sample of 855.

47 people in the sample had hearing aids.

47/855 = 0.0549

Rounding up

0.055

So the correct answer is:

b. 0.055

stealth61 [152]
 Total expense= sum of all expenses incurred 
                       = commission+legal fees+advertising+printing cost+accounting fees

Total amount of shares sold=$ 2000000 x $62.5
                                              =$ 125000000
commission= 4% of the total amount of shares sold                      = .04x12500000
                      =$ 5000000
total expenses= $5000000+$2255500+$450000+$324400+$386000
                        =$8415900
selling expense/share = $8415900/2000000
                                      =$4.21/shareThe total expense per share is $4.21.

KATRIN_1 [288]

Answer:

Step-by-step explanation:

Given

Jar contains 4 white and 4 black marbles

We randomly select 4 marbles out of which 2 are white and 2 are black

Probability that 2 white and 2 black marbles are selected is

P=\frac{^4C_2\times ^4C_2}{^8C_4}

P=\frac{18}{35}

The process is continue for n trails until we choose the correct order

i.e. we have to fail in n-1 trails

For exact n selection Probability is given by

Req.\ Probability=Probability\ of\ failure\ in\ (n-1)\ trials\times Probability\ of\ getting\ exact\ order

=\left ( 1-\frac{18}{35}\right )^{n-1}\times \frac{18}{35}
