A marketing research company desires to know the mean consumption of milk per week among males over age 32. A sample of 710 male

nydimaria [60]

Answer:

(4.5, 4.7)

Step-by-step explanation:

Hi!

Lets call X to the consumption of milk per week among males over age 32. X has a normal distribution with mean μ and standard deviation σ.

$X \sim N(\mu, \sigma)$

When you know the population standard deviation σ of X , and the sample mean is $\hat X$ , the variable q has distribution N(0,1):

$q = \frac{\hat X - \mu}{\sigma} \sim N(0,1)$

Then you have:

$P(-k < q$

This defines a C - level confidence interval. For each C the value of k is well known. In this case C = 0.98, then k = 2.326

Then the confidence interval is:

$(4.6 - 2.326*\frac{0.8}{\sqrt{710}}, 4.6 + 2.326*\frac{0.8}{\sqrt{710}})\\ (4.5, 4.7)$

Raj plotted point L in the coordinate plane below.

Lorico [155]

Answer:

The x- and y-coordinates are switched

Step-by-step explanation:

Here, we want to identify the error in the plot

1.5 units to the left, that is negative x-axis (-1.5)

4 units up is 4

So the coordinate point is (-1.5,4)

So the error on what he gave was that both coordinates were switched

Each fully colored ten block represents 1 whole the number represent above will be divided into 11 equal part how many squares n

e-lub [12.9K]

Given:

Some boxes are fully colored.

Each fully colored ten block represents 1 whole.

The number of colored boxes will be divided into 11 equal part.

To find:

The number of squares need to be colored on each of the 10 blocks.

Step-by-step explanation:

From the given figure, it is clear that,

Number of colored box = 55

The number of colored box will be divided into 11.

$\dfrac{55}{11}=5$

Therefore, 5 squares need to be colored on each of the 10 blocks.
