Answer:
since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
Step-by-step explanation:
Given that the data in the question;
p" = 13/20 = 0.65
Now the test hypothesis;
H₀ : p = 0.9
Hₐ : p < 0.9
Now lets determine the test statistic;
Z = (p" - p ) / √[p×(1-p)/n]
= (0.65 - 0.9) /√[0.9 × (1 - 0.9) / 20]
= -0.25 / √[0.9 × 0.1 / 20 ]
= -0.25 / √0.0045
= -0.25 / 0.067
= - 3.73
Now given that a = 0.05,
the critical value is Z(0.05) = 1.645 (form standard normal table)
Now since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
Answer:
3 games
Step-by-step explanation:
The computation of the maximum number of games that he could buy is shown below:
= Amount available - already spent
= $75 - $28
= $47
If each game cost $15
So, the maximum no of games is
= $47 ÷ $15
= 3.133
= 3 games
Answer:
a)1.5
b)36
c)34
d)5.33333...
e)0
Step-by-step explanation:
1 foot = 12 inches.
Divide total inches by 12:
51 / 12 = 4.25 feet.
The whole number is the number of feet. Now multiply the decimal portion by 12 to get inches:
0.25 x 12 = 3 inches
51 inches = 4 feet 3 inches
The student is 4 feet 3 inches tall
I think it’s A I’m not for sure tho but yeah the Domain is the x the first is -10 and I think the line is on 2 for the other x
