The value of alpha is 0.26, assuming a confidence level of 74%.

<h3>What is the margin of error?</h3>

The significance level α is the probability of making the wrong decision when the null hypothesis is true.

Alpha levels which is also called as significance levels are used in hypothesis tests.

Given

When finding the margin of error for the mean of a normally distributed population from a sample.

The confidence interval = 74% = 0.74.

The value of the alpha is given by;

\rm \alpha =1- Confidence \ interval

Substitute all the values in the formula

\rm \alpha =1- Confidence \ interval\\\\\alpha=1-0.74\\\\\alpha=0.26

Hence, the value of alpha is 0.26, assuming a confidence level of 74%.

Answer:

D 13

Step-by-step explanation:  L+L+W+W=Perimeter

2(1/4x)+2(2x+1)=4.5x+2            

4.5x+2=29        Subtract 2

4.5x=27             Divide by 4.5

x=6                                                            1/4(6)= 1.5 W=1.5      1.5(2)=3

                                                                 2(6)+1=13                  13(2)=26

                                                                                   26+3=29inches perimeter
