A. If there is no middle bias, what proprtion of the best will be in 1 of the 12 middle numbers? b. Conduct a test at the 5% significance level to determine whether middle bias exists c. The middle of the middle are the numbers 17 and 20. If there is no middle bias, what proportion of the bets will be either 17 or 20? d. Test with a 5% significance level to determine whether middle of the middle bias exists.

stethere all not eveanp-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
