A school administrator bought 6 desk sets. Each set consists of one table and one chair. He paid $48.50 for each chair. If he pa

Marrrta [24]

Answer:

b. $62

Step-by-step explanation:

First, we need to add up the cost of all the chairs.

48.5 x 6 = 291

All the chairs together cost $291

Now we can take out the cost of the chairs from the total.

663 - 291 = 372

$372 is what's left over for the cost of all the tables together. So we are going to divide by the number of tables to find out how much each table costs.

372 / 6 = 62

Each table costs $62

Suppose the mean height of women age 20 years or older in a certain country is 62.7 inches. One hundred randomly selected women

zmey [24]

Answer: No, the data provided is not sufficient evidence to conclude that the mean height of women in the city differs from the national mean.

Step-by-step explanation:

Since we have given that

$H_0:\mu =62.7\\\\H_a:\mu \neq 62.7$

Mean height = 61.5 inches

Standard deviation = 4.4 inches

n = 100

So, test statistic value would be

$z=\dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\z=\dfrac{61.5-62.7}{\dfrac{4.4}{\sqrt{100}}}\\\\z=\dfrac{-1.2}{0.44}\\\\z=-2.727$

At 10% level of significance, in two tail test ,

z = 1.28

Since 1.28 > -2.727

So, we will accept the null hypothesis.

Hence, No, the data provided is not sufficient evidence to conclude that the mean height of women in the city differs from the national mean.
