Solution :
Given the average range of the holes drilled = 0.10 cm
The average diameter of the holes drilled = 0.25 cm
The sample size = 4
For the sample size of 4, the factor for control limit for the range (
) = 2.28 (From the table of constants for X-bar and R-chart)
The upper control limit for the R-chart = R-bar x
= 0.10 x 2.28
= 0.228
Therefore, the answer is greater than 0.202 but less than or equal to 0.302
Let's calculate
4/15×285 + 3/20×320 = 124
124 students are participating in these exercises.
Answer:
Step-by-step explanation:
Answer:
mean <median <mode
Step-by-step explanation:
We must calculate the measures of central tendency, which are the mode, the mean and the median.
fashion, value that is most repeated, in this case 87
median, the mean value, how is an even number, the mean is the average of these central numbers, in this case it is 82 and 87
(82 + 87) / 2 = 84.5
average, is the average of all the data, we calculate it like this:
(60 + 74 +82 +87 +87+ 94) / 6 = 80.66
Therefore, the relationship would be like this:
mean <median <mode
