Answer:
Yes, we can conclude that the ship is older than the national average
Step-by-step explanation:
Population mean, μ = 23.6
Sample mean, xbar = 26.7
Sample size, n = 38
H0 : μ = 23.6
H0 : μ > 23.6
The test statistic :
(xbar - μ) ÷ (σ/√(n))
(26.7 - 23.6) ÷ (5.2/√(38))
3.1 / 0.8435513
Test statistic = 3.675
Decision region :
Reject H0 ; if |Tstatistic| > |Tcritical|
Since we are given the sample standard deviation ; we use the T test distribution
df = 38 - 1 = 37
Tcritical at df = 37 ; α = 0.05 ; rigth tailed :
Tcritical(0.05, 37) = 1.687
3.675 > 1.687 ; Hence, we reject H0 and conclude that there is enough evidence that this type of shop is older than the national average.
Answer:
9
Step-by-step explanation:
It’s a ratio.
5/30=x/54
reduce
1/6=x/54
cross multiply
54=6x
x=9
One <em><u>possible answer</u></em> is:
51.0, 51.1, 51.2, 5.13, and 51.4; the list is from least to greatest.
Explanation:
51.0 can be written as 51.00. Comparing this to 50.98, we can see that 51.00 is larger.
51.1 is larger than 51.0; 51.2 is larger than 51.1; 51.3 is larger than 51.2; and 51.4 is larger than 51.3. All of these numbers are also smaller than 51.6.
