The z-statistic can be calculated as the difference in the population mean and sample mean divided by the standard error. The standard error can be calculated as the standard deviation divided by square root of sample size. The standard error: SE = 12/ sqrt(20) = 2.68 The z-statistic: (195 -208) 2.68 = -4.86

Marco wants to build house. United Building Company is offering the rate of $15.75 per square foot + an additional conference fe
marishachu [46]
Let us take the case of United Building Company First
Rate per square foot = $15.75
Conference fee taken per hour = $45.99
Total conferencing hours = 4 hours and 15 minutes
                                         = 4.15 hours
Total square feet of the house = 12226 square feet
Then
The total cost taken by the company = (15.75 * 12226) + ( 45.99 * 4.15) dollars
                                                            = 192559.5 + 190.86 dollars
                                                            = 192750.36 dollars
So the total amount taken by United Building Company is $192750.36 dollars
Now let us take the case of American Contracting Company
Rate per square foot taken = $12.46
Flat conferencing fee taken = $230
Then
The total cost taken by the company = (12.46 * 12226) + 230
                                                           = 152335.96 + 230 dollars
                                                           = 152565.96 dollars
So the total cost taken by the American Contracting Company is $152565.96.
