A certain geneticist is interested in the proportion of Gender 1 and Gender 2 people in the population who have a minor blood disorder. In a random sample of 2000 people of Gender 1, 350 are found to be afflicted, whereas, of 1000 people of Gender 2, 375 tested appear to have the disorder. We are interested in a 97% confidence interval for the difference of proportion of Gender 1 minus the proportion of Gender 2 who have the blood disorder. a) Which function should you use to create a confidence interval

x/3-10=8

x/3=18

x=48

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

i think the answer is b

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
