This set of Total Quality Management TQM Multiple Choice Questions & Answers (MCQs) focuses on Total Quality Management Set 14
Q1 | What is the Sum of Squares of the interaction (AB)?
- 6.075
- 39.48
- 7.19
- 3.89
Q2 | How many replicates of the experiment were performed?
- 1 Replicate
- 2 Replicates
- 3 Replicates
- 4 Replicates
Q3 | You conduct a hypothesis test and you observe values for the sample mean and sample standard deviation when n = 25 that do not lead to the rejection of Ho (null hypothesis). You calculate a p-value of 0.0667. What will happen to the p-value if you observe the same sample mean and standard deviation for a sample n>25?
- Increase
- Decrease
- Stay the same
- May either increase or decrease
Q4 | What does a beta of 0.478 mean?
- That the relationship between the independent and dependent variables is not linear
- That the regression is not significant
- That the correlation is significant
- This means that for every unit increase in your independent variable, your dependent variable increases by 0.478 units
Q5 | Which of the following points are not true when conducting a multiple regression?
- Multiple regression can be used to assess quadratic relationships
- Data must be homogeneous for a multiple regression
- Data must be normally distributed for multiple regression
- Multiple regression can be used to assess linear relationships
Q6 | Which of the following definitions is correct?
- An activity, which results in an outcome, is called an event.
- The probability of an event is expressed in decimal form ranging from -1 to +1.
- The sample space refers to all possible outcomes of an experiment.
- The probability that an event will occur is called the experiment.
Q7 | The discrete random variable X has the probability function (k is a constant): Answerquestion 8 - 10 based on the information given above. The value of k is:
- 1 point
- 1/18
- 1/12
- 1/6
Q8 | A larger standard deviation for a normal distribution with an unchanged mean indicates that‘the distribution becomes:
- narrower and more peaked
- flatter and wider
- more skewed to the right or left
- a change in the standard deviation does not change the shape of the distribution
Q9 | When the k population means are truly different from each other, it is likely that the averageerror deviation:
- Is relatively large compared to the average treatment deviations.
- Is relatively small compared to the average treatment deviations.
- Is about equal to the average treatment deviation.
- Differ significantly between at least two of the populations.
