c. What is the value of the test statistic? d. What is your decision regarding H0? e. What is the p-value? Chapter 10 Exercise 10 Given the following hypotheses: H0 : μ = 400 H1 : μ ≠ 400 A random sample of 12 observations is selected from a normal population. The sample mean was 407 and the sample standard deviation 6.

What is the value for the new sample New Sample Mean = 7 Explanation of work: When the data value is 19:mean = sum of values / # of value 9 = sum/7 sum = 7 x 9 = 63 When that data value is 5 the sum is 63-14 = 49 New mean = 49/7 = 7 7. Using Excel create a histogram and a line graph using the scores in the following table: Note: When you wish to plot one series (the column f in this problem) select only that column. Once you select the column, then you insert the column and line graph. Insert your histogram and line graph here: X 1 2 3 4 5 6 7 8 f 2 1 6 7 4 4 1 1 Line graph 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 f Histogram 8 6 4 2 0 f 1 2 3 4 5 6 7 8

Write assignment statements that perform the following operations with the variables a, b, and c. a) Adds 2 to a and stores the result in b * b=a+2 b) Multiplier b times 4 and stores the result in a * a=b*4 c) Divides a by 3.14 and stores the result in b * b=a/3.14 d) Subtract 8 from b and stores the result in a * a=b-8 4. Assume the variables result, w, x, y, and z are all integers, and that w=5, x=4, y=8, and z=2. What value will be stored in result in each of the following statements? a) Set result = x + y * 12= x + y b) Set result = z + 2 * 4=z * 2 c) Set result = y / x * 2=y / x d) Set result =y – z * b=y – z 5. Write a pseudocode statement that declares the variable cost so it can hold real numbers.
Answer the next four questions using the following set of numbers. Show your work for all questions: 2.0, 3.7, 4.9, 5.0, 5.7, 6.7, 8.5, 9.0 What is the range of the above values? Range is the difference between the lowest value and the highest value. The range of the listed numbers is 9.0-2.0=7.0. What is the median of the above values?
