Please explain answers below. Thank you!
41. A health clinic with four facilities administers a patient satisfaction questionnaire at each of their clinics. Their objective is to determine if patient satisfaction differs across these locations. Which of the following tests would be appropriate.
a.) one sample t
b.) two sample t
c.) multi sample t
d.) ANOVA
42. Consider an I-MR-CHART for plotting the range. The point that is plotted on the chart is calculated by takng the absolute value of the difference between successive observations.
True or False
43. The UCL in an I-MR range chart is 3 standard errors of the mean on either side of the process mean where the estimate of the standard error of teh mean is the average MR divided y 1.128.
True or False
44. The I-MR chart is unusual in that the results of individual samples (samples of size 1) are plotted on a chart. In other process control charts it is the mean of larger samples that is plotted.
True or False
45. In a U-chart, the UCL and LCL change because of the value of ____ can cahnge with every sample.
a.) u
b.) n
c.) IU
d.) c
Explanation / Answer
41. A health clinic with four facilities administers a patient satisfaction questionnaire at each of their clinics. Their objective is to determine if patient satisfaction differs across these locations. Which of the following tests would be appropriate.
Answer : A ANOVA test would be more suitable as there are more than two groups involved here
42. Consider an I-MR-CHART for plotting the range. The point that is plotted on the chart is calculated by takng the absolute value of the difference between successive observations.
Answer : Yes the statement is true as absolute value of difference is taken only.
43. The UCL in an I-MR range chart is 3 standard errors of the mean on either side of the process mean where the estimate of the standard error of teh mean is the average MR divided y 1.128.
True here as in I- MR chart value of d2 is always 1.128.
44. The I-MR chart is unusual in that the results of individual samples (samples of size 1) are plotted on a chart. In other process control charts it is the mean of larger samples that is plotted.
The statement is true.
45. In a U-chart, the UCL and LCL change because of the value of ____ can cahnge with every sample.
In U chart, value of n can change everytime so value of UCL and LCL can change anytime.
