Because the sample size is​ 9, do you need to be concerned about the shape of the population distribution when conducting the t

test in​ (a)? Explain. Choose the correct answer below. A. With a small sample​ size, it is difficult to evaluate the assumption of a skewed distribution.​ However, the distribution may be asymmetric because the mean and the median are not close in value. B. With a small sample​ size, it is difficult to evaluate the assumption that the distribution follows the​ Student's t distribution.​ However, the distribution may be symmetric because the mean and the median are close in value. C. With a small sample​ size, it is difficult to evaluate the assumption of normality.​ However, the distribution may be symmetric because the mean and the median are close in value.

The sample size is 9, so it is difficult to evaluate the conformity assumption with just a little sample to come in the form of a population demographics whenever the t-test is carried out in a. The distribution can be symmetrical since the average or median are close in price, that's why choice C is correct.

Solve for p. Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions. -31p+79 > -59p+81
vesna_86 [32]

Answer:

The answer is

<h2>p > 1/14</h2>

Step-by-step explanation:

-31p+79 > -59p+81

Group like terms

Send the constants to the right side of the expression and those with variables to the left side

That's

- 31p + 59p > 81 - 79

Simplify

We have

28p > 2

Divide both sides by 28

We have the final answer as

<h3>p > 1/14</h3>

Hope this helps you

Answer:

564 tiles

Step-by-step explanation:

there are many ways to solve this soo...

1. convert to centimetres (there are 100 centimetres in 1 metre)

2. the square tiles area = 20*20=400cm

2. find the large area (4.8m x 3.8m or 480cm x 380cm)

480 *380=182400cm

2. find the two smaller areas (1.2m x 1.8m or 120cm x 180cm)

2(120*180)=4.3200cm

3. add to find total area

182400 +43200=225600cm

4. find how many tiles are needed

\frac{225600}{400}= 564 tiles
