Answer:

The median age of the players on Team A is less than the median age of the players on B.

Count to the middle number on each. Median(A) = 18, Median(B) = 19.

The mean age of the players on Team A is less than the mean age of the players on B.

The mean is the average. Mean(A) = 394/22 = 17.9, Mean(B) = 413/22 = 18.7

The IQR for the age of the players on Team A is less than the IQR for the age of the players on B.

Take the median of the upper half, and the median of the lower half.
Q1(A) = 17, Q1(B) = 16.
Q3(A) = 19, Q3(B) = 21.
IQR(A) = 19-17 = 2, IQR(B) = 5.

The first quartile of players' age on Team A is greater than the first quartile of players' age on Team B.

Q1(A) = 17, Q1(B) = 16.

2 — x = 6 3 Any help? Please?

Mama L [17]

X = 9
you multiply both sides by 3 because you have to get rid of it and what you do to one side you do to the other then you divide both sides by 2 to isolate the variable. i hope that makes sense.

Find x and y, given that line WS and line VT are parallel. Show all work!

bulgar [2K]

In the given diagram, the traingles USW and UTV are similar triangles and thus the following ratio equality applies to them.

$\frac{VT}{WS} =\frac{VU}{WU}=\frac{TU}{SU}$ ..........(Equation 1)

Checking the diagram given, we see that:

VT=y, WS=22, VU=8, ST=x-2

WU=WV+VU=12+8=20

TU=5

SU=ST+TU=(x-2)+5=x+3

Thus, substituting the required values in (Equation 1) we get:

$\frac{y}{22}=\frac{8}{20}=\frac{5}{x+3}$

Now, as can be clearly seen, to find y we will use the first two ratios as:

$\frac{y}{22}=\frac{8}{20}$

$y=\frac{8\times 22}{20}=8.8$

In a similar manner, to find the value of x we can use the last two ratios:

$\frac{8}{20}=\frac{5}{x+3}$

After cross multiplication we get:

$5\times 20=8(x+3)$

Which can be simplified as:

$x+3=\frac{100}{8} =12.5$

Thus, $x=12.5-3=9.5$

Therefore, the required answer is:

x=9.5 and y=8.8

he mean age of bus drivers in Chicago is greater than 54.4 years. If a hypothesis test is performed, how should you interpret a

Natalka [10]

Answer:

There is not sufficient evidence to support the claim μ > 54.4.

Step-by-step explanation:

1) Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

2) Solution to the problem

On this case we want to test is $\mu>54.4$ and the system of hypothesi on this case are:

Null Hypothesis: $\mu \leq 54.4$

Alternative hypothesis: $\mu >54.4$

On this case is our decision is FAILS to reject the null hypothesis then we can conclude that we don't have enough evidence to support the claim at the significance level provided. So the correct conclusion would be:

There is not sufficient evidence to support the claim μ > 54.4.
