The mean percent of childhood asthma prevalence in 43 cities is 2.16%. A random sample of 31 of these cities is selected. What i
IceJOKER [234]

Probability that the mean childhood asthma prevalence for the sample is greater than 2.6% is 0.0357 or 3.57 %.

What is Probability ?

Probability is the measure of likelihood of an event.

For a Normal Distribution ,

the z-score formula is given by

\rm Z = \dfrac{X - \mu }{\sigma}

Here \rm \mu\\ is the mean and \rm \sigma\\ is the standard deviation .

It is the measure of the deviation of the data from its central tendency.

Each z-score has a probability value.

It is given in the question that

Mean of 2.16% =  \rm \mu\\ = 2.16

Standard deviation of 1.36% means that  \rm \sigma\\ = 1.36

For Sample of 31 the value of standard deviation is \rm s = \dfrac{\sigma}{\sqrt{n}}

s = 1.36/√31

s = 0.2442

Substituting the values

Z = (2.6 -2.16)/0.2442

Z =1.8

the p value from the graph of z and p , 0.9643

To determine value of probability  more than X is 1 - 0.9643= 0.0357

the

Probability that the mean childhood asthma prevalence for the sample is greater than 2.6% is 0.0357.

And perimeter means we add up all 4 sides so

8+8+3+3= 22

So the dimensions are 8 and 3
