Answer: <em>Hi</em><em> </em><em>Your question lacks some information but i will give you a general solution with similar data found online</em>

answer

a) 15.15%

b) The effect on The probability of smoking is that the p( smoking ) will reduce from 15.15% to 11.70%

Step-by-step explanation:

<u>Using The probit regression </u>

from the attached question ;

for smoking

1 = smokes , 0 = do not smoke

For Independent variable

1 = ban at workplace ,  0 = not ban at workplace.

sex :  male = 0 , female = 1

<u>a) Assuming Mr. A is not subject to a workplace smoking ban </u>

P ( Mr. A  smokes ) = 15.15%

<u>b) Assuming Mr. A is subject to a workplace smoking ban</u>

determine effect  on P ( Mr. A smokes )

The effect on The probability of smoking is that the p( smoking ) will reduce from 15.15% to 11.70%

without building a model tell whether a long row of 8 cubes or a cube made from 8 would have a greater volume. explain
Viktor [21]
I'm presuming that the 'large cube' is made from 8 cubes the same size as the 8 cubes in the long row. They both have the same volume, the only difference between them is that they are arranged in a different order. Hope this helps. If not feel free to ask again and give more information.

Enrollment in a school district is currently 1250 students and is decreasing at approximately 3% per year. Enter the number of y
FromTheMoon [43]

Answer: the number of years is 7.3 years

Step-by-step explanation:

We would apply the formula for exponential decay which is expressed as

A = P(1 - r)^ t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 1250

A = 1000

r = 3% = 3/100 = 0.03,

Therefore

1000 = 1250(1 - 0.03)^t

1000/1250 = (0.97)^t

0.8 = 0.97^t

Taking log of both sides, it becomes

Log 0.8 = tLog 0.97

- 0.0969 = - 0.0132t

t = - 0.0969/- 0.0132t

t = 7.3 years
