Answer: D) 0.0013
Step-by-step explanation:
Let x be the random variable that represents the lengths of rods.
As pr given , we have
n=100 ,
z-score :
For x= 119.985 inches , we have
Using the standard z-table , we have
The probability that Claude's sample has a mean less than 119.985 inches is
Hence, the probability that Claude's sample has a mean less than 119.985 inches is 0.0013.
The steps in achieving the answer for the simplification are as follows:
1. The least common multiple of the denominators of the terms of the given is ab.
2. Multiply the expression with ab, such that,
(xy/a - 1/b) x (ab)
3. Simplifying,
xyb - a
4. Writing ab as the denominator of the expression in number, we get the final answer which is equal to,
<em> (xyb - a)/ab
</em>
