Step-by-step explanation:
"<u>A two sample t test for a difference in means was conducted to investigate whether the average time to swim a lap with the freestyle stroke is different from the average time to swim a lap with the butterfly stroke</u>."
Answer:
Mean x¯¯¯ 2.2
Median x˜ 1
Range = 9
Q1 --> 0
Q2 --> 1
Q3 --> 3
Interquartile range: 3
Mean Absolute Deviation (MAD): 2.08
Standard deviation : 2.71
Step-by-step explanation:
1. Number of absent students:
0,1,1,0,3,2,5,1,9,0
Find the:
Mean
0, 0, 0, 1, 1, 1, 2, 3, 5, 9/10
= 22/10
= 2.2
Median
0, 0, 0, 1), 1, 1, (2, 3, 5, 9
= 1 + 1/2
= 2/2
= 1
Lower quartile
Upper quartile
Range
= 9 - 0
= 9
Interquartile range = 3
Mean absolute deviation = 2.08
Standard deviation = 2.71

Discussion:
For every value of x, g(x) = f(x) -1 meaning that the y-value of g(x) is 1 less than the corresponding y value of f(x). So the graph of g(x) is "below" f(x) or it is translated 1 unit downward from f(x)

If they are just looking for the “inverse” which means flip it it’ll be 5radical (which the the v shape looking bar) x-4 = h(x)
