In order to solve this problem easily you coin this method: Find the squares of 0.13 and 0.14. They are respectively 0.0169 and 0.0196. Irrational numbers are going to located between this interval, considering that we are not counting perfect squares. $\sqrt{0.0168} , \sqrt{0.017} , \sqrt{0.0175}$ are the three possible answers.

Suppose that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in.

nadya68 [22]

Answer:

Step-by-step explanation:

Given that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in. and a standard deviation of sigma equals 1.2 in.

We have to find values of x such that

$P(X\geq a) \leq 0.01\\$ and

$P(X\leq b) \leq 0.01$

a=2.33 and b =-2.33 as z values

Let us convert to X values

$x=22.1-2.33(1.2) \\x=22.1+2.33(1.2)\\$

i.e. values below 19.304 and above 25.496

Hence for x below 19.304 and above 25.496 are significantly low and high.

24.2 length is not significantly high.
