Answer:
-25.5
Step-by-step explanation:
Hi Baby girl,
59.2 - 84.7 can be worked out this way:
First calculate 84.7 - 59.2 on your rough paper
That gives 25.5
Finally make your answer a negative number (since the question is about subtracting a larger number from a smaller number)
The answer therefore is -25.5
Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
= 1.36/√16
= 1.36/4
= 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
= 3.8/(1.36/√16)
= 3.8/(1.36/4)
= 3.8/0.34
= 11.18
The slopes of two parallel lines are equal! They are identical to one another
49/100 is equal to .49 in decimal form, and now we just need to add the 4 wholes. This is equal to 4.49
