Answer:
C
Step-by-step explanation:
Answer:
$24
Step-by-step explanation:
3/5 of $40
Whenever you hear the word "of" in a mathematical equation, it usually means multiplied by. So 3/5 * 40 is equal to 120/5 which is 24
Start with
Add 2 to both sides:
Divide both sides by 7:
Which is true if
If we choose the positive alternative, we have
Otherwise, we have
Answer:
a.) one sample t test
b.) H0 : μ = 59.3
c.) H1 : μ > 59.3
d.) μ = 59.3 ; σ = 39.84
e.) xbar = 79.4 ; s = 61.36
Test statistic = 3.16
Step-by-step explanation:
Given the sample data:
49.00 49.00 49.00 49.00 49.00 63.00 63.00 63.00 63.00 63.00 199.00 199.00 199.00 199.00 199.00 38.00 38.00 38.00 38.00 38.00 48.00 48.00 48.00 48.00 48.00 49.00 63.00 199.00 38.00 48.00
Sample size, n = 30
Using calculator :
xbar from the data above = 79.4
Standard deviation = 61.359
H0 : μ = 59.3
H1 : μ > 59.3
Test statistic :
(Xbar - μ) ÷ (σ/sqrt(n)
σ = 34.83
(79.4 - 59.3) ÷ (34.83/sqrt(30))
20.1 ÷ 6.359
Test statistic = 3.16
Answer:
12/11
Step-by-step explanation:
11/11=1
1/11=1/11
11/11+1/11=12/11
