Answer:
5 or more raise the score,
4 or less give it a rest.
9 is in the tenth place. "5 or more raise the score", 9 is more than 5 so you would "raise the score" and the answer would be 1.3. the 2 changes because we are rounding to the nearest tenth.

10 crayons in all.
P (red) = 4/10 or 2/5
P (2nd red) = 3/9 =1/3 since there are only 9 crayons left from which to choose and only three of them are red (since we already pulled one).
2/5 x 1/3 = 2/15 = P (2 red) with no replacement.
Answer:
The lower bound of a 99% C.I for the proportion of defectives = 0.422
Step-by-step explanation:
From the given information:
The point estimate = sample proportion 
= 0.55
At Confidence interval of 99%, the level of significance = 1 - 0.99
= 0.01
Then the margin of error 
E = 0.128156
E ≅ 0.128
At 99% C.I for the population proportion p is: 
= 0.55 - 0.128
= 0.422
Thus, the lower bound of a 99% C.I for the proportion of defectives = 0.422
