g An article reported the results of a survey of 400 elementary school teachers and 500 high school teachers. Of the elementary

school teachers, 100 said they were very satisfied with their jobs, whereas 200 of the high school teachers were very satisfied with their work. We wish to do hypothesis testing to check that true proportion of elementary school teachers and high school teachers who were very satisfied with their jobs differs from each other. Write the formula and calculate the value of the estimate of the standard error of the sample statistics, you would use in finding test statistic, assuming null hypothesis is true.

Brittany buys 2.55 pounds of turkey for $5.96 per pound and 3.7 pounds of
Galina-37 [17]

Answer:

Brittany needs another $3.7405.              

Step-by-step explanation:

Per pound Cost of turkey = $5.96 per pound

The amount Brittany buys the turkey = 2.55 pounds

Brittany's cost for turkey = 2.55 × $5.96 = $15.198

Per pound cost for cheese = $3.35 per pound

The amount Brittany buys the cheese = 3.7 pounds

Brittany's cost for cheese = 2.55 × $3.35 = $8.5425

So,

Brittany's total cost = Turkey cost + Cheese cost

                                = $15.198 + $8.5425

                                = $23.7405

As brittany gave the clerk 20 dollars.

So, the amount she further needs will be:

$23.7405 - $20 =  $3.7405

Therefore, Brittany needs another $3.7405.
