A car company advertises that thir Super Spiffy Sedan averages 29mpg (miles per gallon). You randomly select a sample of Super Spiffies from local car dealerships and test their gas mileage under similar conditions.

You get the following MPG scores:

33 27 32 34 34 28 27 31

Note: SSx = 63.50

Using alpha =.01, conduct the 8 steps to hypothesis testing to determine whether the actual gas mileage for these cars differs significantly from 29mpg.

Create frequency table (including  include class interval, frequency, relative frequency and cumulative relative frequency. ) and frequency polygon.

Please explain HOW for a thumbs up!! TY

Please let me know how to make code sort.

If you put sort (sort 1000 6 5 4 3 2 1, not separate), you will get 1 2 3 4 5 6 1000.

sort 50 300 27 5

5 27 50 300

public static void main (String[] args) {
       Scanner scnr = new Scanner(System.in);
       String a = "";
           a = scnr.nextLine();
           String[] b = imput.split(" ")

if (b[0].equalsI("sort")) {

}

Please do not change above code.

To test whether the mean time needed to mix a batch of material is the same for machines produced by 4 manufacturers, the Jacobs Chemical Company obtained the following data on the time (in minutes) needed to mix the material.

What is the p value?

Does the data provide strong evidence evidence against Ho or weak evidence?

Are the mixing machine considered all equal?

At one hospital there is some concern about the high turnover of nurses. A survey was done to determine how long (in months) nurses had been in their current positions. The responses (in months) of 20 nurses were as follows. 27 6 9 18 29 40 31 46 16 12 11 27 33 30 32 15 24 35 12 40 Make a box-and-whisker plot of the data. (Select the correct graph.) Find the interquartile range. (Enter an exact number.) IQR =

1) Given Arr[10] = {7, 9, 13, 15, 16, 10, 12, 5, 20, 27}

Write a program to count number of EVEN and ODD items. Do a screen output of your result.

2) Given Arr[10] = {7, 9, 13, 15, 16, 10, 12, 5, 20, 27}

Write a program to construct array ODD[] and EVEN[] from Arr[10] as you realize ODD[] consists of odd number and EVEN[] consists of even number.

Case: A New Business

Mr. Khalid, a young entrepreneur who has worked in various restaurants throughout high school and college, has decided to develop a new food service concept that focuses primarily on takeout of home-cooked food for busy professionals on their way home from work. The restaurant would also have a small dining area for customers who wish to eat the food there. Because this prospective business will have to compete with other traditional local restaurants, Mr. Khalid wants to ensure that this business will compete on quality and develop a strong quality reputation.

Question: Explain Marketing perspective of Quality for the new business?
