An independent research firm conducted a study of 100 randomly selected children who were participating in a program advertised to improve mathematics skills. The results showed no statistically significant improvement in mathematical skills, using a significance level of 0.05. The program is effective, which of the following would be an appropriate method for increasing power in this context?
a. Increase the sample size to 200 children.
b. Use a two-sided test instead of a one sided test.
c. Decrease the sample size.
d. Use alpha-0.01 instead of a-alpha.
e. Use a one sided test instead of a two-sided test.
Answers
Answer:
b) use a two-sided test instead of a one sided test.
Step-by-step explanation:
If we are using a significance level of 0.05, then the two-tailed test assigns half alpha to test for statistical significance in one direction and half alpha to test statistical significance in the other direction. This implies that .025 is present in each tail of the test statistical distribution. When using the two-tailed test, regardless of the direction of the relationship you assume, we test the possibility of the relationship in both directions.

Jose wants to plan a skate party for his younger cousin's birthday. Skate Land charges a $65 flat fee and $7.50 per person.
Skate Land uses the equation C = 7.50p + 65 (C = total cost; p = number of people ) to calculate the total cost
based on the number of people attending. Find the total cost, C, of the birthday party if Jose invites 30 friends and family
members.
Answers
Answer:
$290
Step-by-step explanation:
We can use the equation that Skate Land created to find the total cost
C = 7.50p + 65
p = people so if we have 30 people, we have to solve 7.50 x 30
C = 225 + 65
we can now add the flat fee of $65 to get the total cost for the birthday part
C = $290

Find the slope of a line perpendicular to the equation: 3x – 2y = 6
Answers
Answer:
3/2x
Step-by-step explanation:
so
y=mx+c
-2y=-3x+6
2y=3x-6
y=3/2x-3
So the gradient of the perpendicular would be
m= -2/3
find the x and y
y=3/2(0)-3
=-3
(0)=3/2x-3
x=2
So
Substitute them all into
y=mx+c
-3=-2/3(2)+c
c=-5/3
So
y=-2/3x-5/3

A: –10 or less
B: –10 or greater
C: 12 or less
D: 12 or greater

D) 12 or greaterStep-by-step explanation:
Total money Charnika has = $500
The money she wants to save = $200
Amount of money she can spend = $ (500 - 200)
= $300
Amount of money withdrawn in every week = $25
The number of weeks the money can be withdrawn = $ (300÷25)
= $ 12
