Answer:

{27.5, 29, 34}

Step-by-step explanation:

Arrange in increasing order :

24, 27, 28, 28, 29, 31, 32, 36, 38

Lower Quartile :

24 + 27 + 28 + 28 / 4
107/4
26.75 ≈ 27.5 (closest based on options)

Median :

5th term
29

Upper Quartile :

31 + 32 + 36 + 38 / 4
137/4
34.25 ≈ 34

Answer:

{27.5, 29, 34}.

Step-by-step explanation:

In order they are

24 27 28 28 29 31 32 36 38

The Median = middle value = 29.

Lower quartile = mean of 27 and 28 = 27.5.

Upper quartile = mean of 32 and 36 = 34.

Twelve more than 3 times a number is more than the opposite of 11

aleksley [76]

Answer: n > $\frac{-23}{3}$

Step-by-step explanation:

1. So, to understand this you need to understand that the opposite of 11 is -11.

2. Use the formula 3n+12>-11.

3. Subtract 12 from both sides (3n>-23)

4. Divide by 3 on both sides. (n> $\frac{-23}{3}$ )

5. You can go a step further and simplify into -7 $\frac{2}{3}$ .

6. n > $\frac{-23}{3}$

Suppose a normal distribution has a mean of 62 and a standard deviation of4. What is the probability that a data value is betwee

saw5 [17]

SOLUTION

From the given data the mean is 62 and standard deviation is 4

It is required to find the probability that a data value is between 57 and 62

That is:

$P(57\lt x\lt65)$

The z scores is calculated using:

$z=\frac{x-\mu}{\sigma}$

Using the x values it follows:

$z=\frac{57-62}{4}=-1.25$

Also,

$z=\frac{65-62}{4}=0.75$

Thus the required probability is:

$P(-1.25The proability is:[tex]P(-1.25This can be expressed as percentage as:[tex]P(-1.25\lt z\lt0.75)=66.8\%$

Therefore the correct option is C
