Milk is a good source of many vitamins that can help us stay healthy. FDA recommends that the average vitamin A concentration fo
r whole milk should be 200.9220 micrograms per liter. A first study in 2016 collected a sample of 34 whole milk bottles and found the average vitamin A concentration was 207.9068 micrograms per liter with a standard deviation of 11.8841 micrograms per liter. A medical researcher wants to use this information to determine the sample size required to estimate the mean vitamin A concentration in whole milk at 95% confidence with a margin of error of no more than 0.3656 using the following formula, n = (t*sME)2. Note: Numbers are randomized for each instance of this question. Use the numbers given above. What is the degrees of freedom used to calculate the t* multiplier for this scenario?
This is a piecewise-defined function because it is defined by two or more equations over a specified domain is. The graph of this function is shown below. So this functions is continuous because its graph is a single unbroken curve. So the function is defined be the line 3x - 2 when x = 3 and the output here is y = 7
