AlladinOne [14]

Answer:

The length of each side of the base is 229\ m

Step-by-step explanation:

we know that

The area of a square is equal to

A=b^{2}

where

b is the length side of a square

In this problem we have

A=52,441\ m^{2}

so

substitute in the formula

52,441=b^{2}

Square root both sides

b=\sqrt{52,441}\ m

b=229\ m

Assume that IQ scores are normally distributed with a mean of 100 and a standard deviation of 16. If 100 people are randomly sel
laiz [17]

Answer:

0.03 is  the probability that for the sample mean IQ score is greater than 103.      

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100

Standard Deviation, σ = 16

Sample size, n = 100

We are given that the distribution of IQ score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Standard error due to sampling =

\dfrac{\sigma}{\sqrt{n}} = \dfrac{16}{\sqrt{100}} = 1.6

P( mean IQ score is greater than 103)

P(x > 103)

P( x > 103) = P( z > \displaystyle\frac{103 - 100}{1.6}) = P(z > 1.875)

= 1 - P(z \leq 1.875)

Calculation the value from standard normal z table, we have,  

P(x > 103) = 1 - 0.970 =0.03= 3\%

0.03 is  the probability that for the sample mean IQ score is greater than 103.
