Answer:
Hypothesis testing of ' significance of difference between means'
Step-by-step explanation:
Study conducted to tests whether oxygen level prior SAT score improves test score. This can be done through - Hypothesis testing of ' significance of difference between means'.
Where x1 & x2 represent mean values of SAT test score before (or without) & after (or with) oxygen.
Null hypothesis [H0] = x1 = x2 , Alternate Hypothesis [H1] : x1 < x2
Answer: 17,094 feet
Step-by-step explanation:
5280 ft. in 1 mile
5280 x 3= 15,840
15,840+1,254= 17,094 ft.
Answer:6.41
Step-by-step explanation:

=6.41
The entire length of the line, AE, is 38. We are asked to find the length from point C to point E.
AB and BC are both 5 units in length. The length from point B to point D is 17. So, if we subtract 5 from 17, we get 12.
The length between point C and point D is 12. DE appears to be of the same distance. So, DE is also 12.
12 + 12 = 24
So, CE = 24.
