b) -1.0389
c) 0.1631
Step-by-step explanation:
We are given the following in the question:
9.7, 9.9, 10.3, 10.1, 10.5, 9.4, 9.9, 10.1, 9.7, 10.3
a) sample mean and standard deviation
Formula:
where are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 1.009
b) observed value of the t-statistic
Formula:
Putting all the values, we have
c) probability of these statistics (or worse) if the true mean were 10.1 mm
Degree of freedom = n - 1 = 9
Calculating the value from the table
0.1631 is the the probability of these statistics (or worse) if the true mean were 10.1 mm
Answer:
The answer is below
Step-by-step explanation:
When computing quartile and decile, the data must be arranged in ascending order.
Given the data points:
13 13 13 20 26 26 29 31 34 34 35 35 36 37 38 41 41 41 42 43 46 47 48 49 53 55 56 62 67 82
The numbers are arranged in ascending order. The total number of terms is 30.
