Answer: Standard error of the average annual salary SE = $597.6
Step-by-step explanation:
Given;
Standard deviation = r = $5,000
Number of samples = n = 70
Mean = $50,000
To derive the standard error of mean SE. It is given as
SE = r/√n
SE = $5,000/√70
SE = $5,000/8.3666
SE = $597.6
Answer: 1.5
Step-by-step explanation:Let the standard deviation of the shoe size be represented by ' ' and the mean shoe size be represented by ' = 7.5'. Also, the sizes of the shoe be represented by ' '. So, . Hence, the standard deviation of the shoe size data for the math class is 1.5.
Answer:
f = -2.75
steps:-
2(f - 2) = 3 (2f + 5) 8
2f - 4 = 6f + 15 - 8
2f - 6f = 15 - 8 + 4
-4f = 15 - 8 + 4
-4f = 11
f = 11 ÷ ( - 4)
f = -2.75
