Answer:
There is sufficient statistical evidence to state that the average hours of productive work, after announcing the stimulus, has increased significantly
Step-by-step explanation:
To solve this problem, we run a hypothesis test about the difference between population means with dependent samples. Consider the differences in average hours of productive work after the stimulus minus average hours of productive work before the stimulus.
Difference in the null hypothesis (Do) = 0
Sample size (n) = 10
Mean of the sample differences (DM) = 0.19
Standard deviation of the sample differences (SM) = 0.1729
Significance level = 0.01
H0: Do = 0
Ha: Do> = 0
Test statistic =
Right critical T value (for 0.01) = 2.8214
Calculated statistic =
p-value = 0.00350
Since, the value of the test statistic is greater than the value of the calculated statistic, the null hypothesis is rejected. There is sufficient statistical evidence to state that the average hours of productive work, after announcing the stimulus, has increased significantly. The p - value is 0.00350.
M = 5h + 10.....so basically we solve for h subtract 10 from both sides m - 10 = 5h divide both sides by 5 (m - 10)/5 = h
Given:
The actual length of side y is 22cm.
To find:
The length of side x by using the scale drawing.
Solution:
We know that the corresponding sides of original figure and scale drawing are proportional.
Therefore, the length of side x is about 28.286 cm.
