Chapter 14.2, Problem 6BSC
Control Charts for p. In Exercises 5-12, use the given process data to construct a control chart for p. In each case, use the three out-of-control criteria listed near the beginning of this section and determine whether the process is within statistical control. If it is not, identify which of the three out-of-control criteria apply.
6. Euro Coins Repeat Exercise 5, assuming that the size of each batch is 100 instead of 10,000. Compare the control chart to the one found for Exercise 5. Comment on the general quality of the manufacturing process described in Exercise 5 compared to the manufacturing process described in this exercise.

Eighteen participants took part in an experimental study that consisted of three levels: normal classroom teaching, normal classroom teaching with tutors, and an experimental teaching method to increase student scores on a statistics exam. Your data set includes the following variables:
Treatment
(1 - normal classroom teaching; 2 - normal classroom teaching with tutors; 3 - experimental teaching method)
Gender
(1 – female; 2 – male)
Pre-test score
(higher scores represent better student performance on a statistics exam)
Post-test score
(higher scores represent better student performance on a statistics exam)
Stanford-Binet Intelligence Test scores (IQ)
The number of hours the student studied per week.
Do test scores at pre-treatment differ from test scores at post-treatment? Note, this analysis should be conducted ignoring the treatment group they are in.
Select an appropriate statistical test and state teh hullhypothesis.
A method or a set of procedures of using sample data to estimate a population parameter is called
A. statistical inference
B. statistical interference
C. statistical appliance

10.50 Recess and Wasted Food. E. Bergman et al. conducted a
study to determine, among other things, the impact that scheduling
recess before or after the lunch period has on wasted food for students in grades three through five. Results were published in the
online article “The Relationship of Meal and Recess Schedules to
Plate Waste in Elementary Schools” (Journal of Child Nutrition and
Management, Vol. 28, Issue 2). Summary statistics for the amount of
food wasted, in grams, by randomly selected students are presented
in the following table.
Lunch before recess Lunch after recess
¯ x1 = 223.1 ¯ x2 = 156.6
s1 = 122.9 s2 = 108.1
n1 = 889 n2 = 1119
At the 1% significance level, do the data provide sufficient evidence to
conclude that, in grades three through five, the mean amount of food
wasted for lunches before recess exceeds that for lunches after recess?

- A bank branch located in a commercial district of a city has the business objective of developing an improved process for serving customers during the noon-to-1:00 P.M. lunch period. The waiting time, in minutes, is defined as the time the customer enters the line to when he or she reaches the teller window. Data are collected from a sample of 15 customers during this hour.

- In an attempt to cut university expenditure, the Dean at a University inquires about reducing the four month training period of dogs at the BCIE. The trainers at the BCIE agree with the proposal but only if the dogs can reach the 70% success threshold that is required of dogs working with anxiety patients. The trainers design an experiment in which they measure the training success of 20 dogs after one month, two months, three months and four months of training. The attached CSV file contains the data that was collected for this experiment. What can you conclude from the results of this experiment?

- 9. A data set from a study that examined the effect of a specific diet on blood pressure is provided on the course web page. Participants (n = 72) were randomly assigned either to a group that was put on the diet (Diet = Present) or to a group that was not put on the diet (Diet = Absent), and researchers wanted to know whether the diet had a significant impact on blood pressure. The other variables in the data set are drug (X, Y, or Z) and a biofeedback condition (present or absent), but we wish to focus on the diet effect here. Test whether there is a statistically significant difference in mean blood pressure between the diet groups. Report the appropriate test statistic, df, and p-value.
