Answer:
1. F
2. (2,2)
3. points P and E
Step-by-step explanation:
i cant see the lines clearly, soo all i can say is that:
- x is the horizontal line, y is vertical
- quadrant I all positive
- quadrant II x negative, y positive
- quadrant III all negative
- quadrant IIII y positive, y negative
- for every line the point passes, it counts as 1
- each point does not have a certain order to go in the chart
sorry, but this is the best i can do for now! make sure your pictures are clear next time :D
Answer:
Z= 0.253
Z∝/2 = ± 1.96
Step-by-step explanation:
Formulate the null and alternative hypotheses as
H0 : u1= u2 against Ha : u1≠ u2 This is a two sided test
Here ∝= 0.005
For alpha by 2 for a two tailed test Z∝/2 = ± 1.96
Standard deviation = s= 15
n= 10
The test statistic used here is
Z = x- x`/ s/√n
Z= 2058- 2046 / 15 / √10
Z= 0.253
Since the calculated value of Z= 0.253 falls in the critical region we reject the null hypothesis.
There is evidence at the 0.05 level that the doors are too short and unusable.
