Within a really large population items either have or do not have a particular characteristic. We take a sample of size 137 of that population. Within that sample we find that we have 115 are dogs under 20 pounds. Calculate the 90% confidence interval for the true proportion of dogs that weigh under 20 pounds.

step-by-step explanation:

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

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!
