Suppose the population standard deviation is σ = 5 , an SRS of n = 100 is obtained, and the confidence level is chosen to be 98%
beks73 [17]

Answer:

1.165.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.98}{2} = 0.01

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.01 = 0.99, so z = 2.33

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

In this problem, we have that:

\sigma = 5, n = 100. So

M = z*\frac{\sigma}{\sqrt{n}}

M = 2.33*\frac{5}{\sqrt{100}} = 1.165

So the correct answer is:

1.165.

Fred’s company is planning a new logo. The diagrams show two similar versions of the planned logo.
seraphim [82]

Answer:

a=7.2*1.5=10.8 cm

b=6.3/1.5=4.2 cm

\pounds 4.48*2.25=\pounds 10.08

Step-by-step explanation:

<u>Proportional Geometric Shapes </u>

A) We are given two similar shapes of a logo. They are to be proportional. We only need to find the proportion ratio of two of them to find the rest of the lengths.

The upper sides have 7.5 cm and 5 cm respectively. This gives us the ratio

\displaystyle r=\frac{7.5}{5}=1.5

Which means all the measures of the smaller logo are 1.5 smaller than those of the larger. This means  

b=6.3/1.5=4.2 cm

a=7.2*1.5=10.8 cm

B) To paint the logos, we need to cover its surface, so the ratio of the surface is 1.5*1.5=2.25

This means the cost to paint the larger logo is  

\pounds 4.48*2.25=\pounds 10.08
