A researcher selects a sample of 49 participants from a population with a mean of 12 and a standard deviation of 3.5. What is th

enot [183]

Answer:

The probability of selecting a sample mean of 13 or larger from this population is 0.0228

Step-by-step explanation:

A researcher selects a sample of 49 participants from a population with a mean of 12 and a standard deviation of 3.5.

$n = 49$

$\mu = 12$

$\sigma = 3.5$

We are supposed to find the probability of selecting a sample mean of 13 or larger from this population i.e. $P(x\geq 13)$

$Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

$Z=\frac{13-12}{\frac{3.5}{\sqrt{49}}}$

Z=2

Refer the z table

$P(Z$

$P(x\geq 13)=1-P(Z$

Hence the probability of selecting a sample mean of 13 or larger from this population is 0.0228

Find the area of the composite figure.

klio [65]

Answer:

174 feet squared

Step-by-step explanation:

The figure is composed of a rectangle and a right triangle

Therefore,

Area of the composite figure = area of the rectangle + area of the right triangle

= (L*W) + (½*b*h)

L = 18 ft

W = 9 ft

b = 18 - (6 + 6) = 6 ft

h = 4 ft

Plug in the values into the equation

Area of the composite figure = (18*9) + (½*6*4)

= 162 + 12

= 174 ft²
