$8.50 x 1.06 = $9.01
The 1.06 comes from the cost of the whole shirt (1) plus the amountof tax (.06) added together.
First of all, try to understand the questions then try to make a pair of linear equations. After that make the coefficients of x or y equal in both RFD equations by multiplying them by suitable values then add or subtract them ,in such a way which will terminate any one of the variables. Then find the value of left variable. After that just put the value you have found just now In any of the equations and you'll really get the value of the second variable too.
According to the sample size, it will be necessary to approximate the data through the normal distribution and through this calculate the standard deviation to obtain both the average, the standard deviation and the obtained deviation. Here the sample size is 40.
Approximately the distribution of proportion is a Normal distribution using the CLT. the mean will be 0.78, then we have that the standard deviation is,



Then the distribution will be normal with the values of 0.78 to 0.0655 for the mean and the standar deviation respectively.
<em>Normal (0.78,0.0655)</em>
