I NEED IT NOW PLEASE AND THANK YOU

Consider the following hypotheses.

H

0

H0: The average proportion of all lightbulbs that are defective is 0.10.(D=0.10)

(D=0.10).

Ha

Ha: The average proportion of all lightbulbs that are defective is greater than 0.10.(D>0.10)

(D>0.10)

A reasonable test statistic for the hypotheses is W, defined as

e) Calculate W using your answer to part (d).

f) Chebyshev's inequality states that the proportion of any distribution that lies withinkstandard errors of the mean is at least

11

k

2

11k2.

Use Chebyshev's inequality and the value ofWto decide whether there is statistical evidence, at the significance level of=0.05

=0.05, thatD, the average proportion of all lightbulbs that are defective, is greater than 0.10.
