Answer:
H0 : μ1 = μ2
H0 : μ1 < μ2
Step-by-step explanation:
Given :
Early studiers, group 1, mean μ1
Late studiers, group 2 ; mean, μ2
To test the claim that students who study earlier have an average score that is less than the average score for students
The null hypothesis ; there is no difference in average score
H0 : μ1 = μ2
Alternative hypothesis is early studiers means is less than average score of late studiers
H0 : μ1 < μ2
Answer:
(0,-3) because its the coordinate
Answer:
975 bulbs
Step-by-step explanation:
1/40 bulbs were defective
That means 1-1/40 were not defective
40/40 - 1/40 = 39/40 were not defective
We have 1000 bulbs
Multiply the number of bulbs by the fraction that is not defective to get the number of bulbs that should not be defective.
1000 * 39/40 = 975 bulbs
For this question, set up an equation. 60 times what decimal is 27?
60x=60
x=0.45
Convert this decimal to a percentage by multiplying it by 100:
45%
For this question, set up an equation. 55% (or 0.55) times what number equals 22?
0.55x=22
<em>*Divide both sides by 0.55*</em>
x=40
Hope this helps!!
