Answer:

14.34%

Explanation:

To find the percentage of returned surveys over the total we divide and then multiply:

(717/5000)*100= 14.34%

The response rate appears to be low because it is less than 50% (which would be 2500 return surveys). Some statistical studies agree that 30 is the minimum number of observations a study must have, but this number does not ensure statistically significant results.  

The problem with a very low response rate is that survey´s answers does not significant represent the study population characteristics and so we cannot make inferences, correlations or regressions that are statistically significant. In this case, the conclusions that scientists make about association between the left-handed population and right-handed population with the use of cell phone calls could be wrong or not represent the population characteristics, which means answers are not trustful.

aleksley [76]

Answer: 0.050

Explanation:

Mean = 18

USL = 18.6

LSL = 17.4

SD = 1.25

Cpk = Min{(mean - LSL / 3*sd), (USL - mean / 3*sd)}

earnstyle [38]

Answer:

d. $1,875 unfavorable

Explanation:

Direct material quantity variance is computed as;

= (AQ - SQ) × SP

AQ = Actual quantity = 6,300 units

SQ = Standard quantity = 14,200 / 2 = 7,300 units

SP = Standard price = $0.80

Direct material quantity variance

= (6,300 - 7,300) × 0.80

= -1,000 × $0.80

= -1,875 unfavorable
