The Statistical Abstract of the United States (109th edition) reported that the mean age of all U.S. registered merchant vessels
motikmotik

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:

1.  x > 4

2.  m < 2

3.  x > 2

4.  x < -6

Step-by-step explanation:

These 4 inequalities will be solved the same way we solve equations. We take variables to one side and numbers to another and use algebra to solve. Each of them are solved shown below:

1.

4+6x

so x is greater than 4, we can write (variable first):

x > 4

2.

m+16>8m+2\\16-2>8m-m\\14>7m\\\frac{14}{7}>m\\2>m

so m is less than 2, we can write:

m < 2

3.

5x-1>13-2x\\5x+2x>13+1\\7x>14\\x>\frac{14}{7}\\x>2

so x is greater than 2, we can write:

x > 2

4.

-3x-2>-x+10\\-2-10>-x+3x\\-12>2x\\\frac{-12}{2}>x\\-6>x

so x is less than -6, we can write:

x < -6

The ratios in the table must be equivalent if it is to be filled in with something other than random numbers.

__

The second row is 10/4 = 2.5 times the first.

The first row is 4/10 = 0.4 times the second.
