In a random sample of 60 computers, the mean repair cost was $150. Assume the population standard deviation is $36. Construct a 95% confidence interval for the population mean.
Answer:
The 95% confidence interval for the population mean is between $140.89 and $159.11.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.96\frac{36}{\sqrt{150}} = 9.11[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 150 - 9.11 = $140.89
The upper end of the interval is the sample mean added to M. So it is 150 + 9.11 = $159.11
The 95% confidence interval for the population mean is between $140.89 and $159.11.

Answer:
Pie charts can generally be used instead of bar graphs
Step-by-step explanation:
A pie chart can be used instead of a bar chart. A pie chart is an alternative to the bar chart. Both of these can be regarded as data visualization tools. The pie chart shoes us generally how several parts makes up a whole. While the bar chart uses rectangular bars to show us the proportion of each of the categories of data
The statement which is true among the given group of options is; Pie charts can generally be used instead of bar charts.
Data visualization toolsPie charts can be used as substitutes for bar charts. This stemmed from.the fact that both tools are data visualization tools.
On this note, pie charts can be used to replace the bar charts even though pie charts entails dividing the 360° angle in a circle in respective ratios.

The radius of a circle is 9 centimeters. What is the length of a 96° arc?
Wrong answer but unique technique to consider: i think i inversed the ratio but i think its right
Pi = circumference/diameter
X/18 centimeters =pi
X is whole circumference 18pi cm you need to convert radians to degrees and get partial arc1 pi is 180 degrees so ratio of
Was the error inverse ratio 96/180?
180/96*18
Error here factor of 72 not 96
18*2*3*3*10/2*3*12 [edit factor should be 2 4 12 ]cancel out factors to reduce
180/4 =45cm
Correction
180*3/4*4
So answers i got are 45 cm corrected as 33.75 cm still way more than total circumference of 18pi 56cmapprox and 9.6cm both are wrong according to calculator online
Please note I canceled out pi by using is degree ratio
Double check i may be wrong
Step-by-step explanation:
Answer:
Solution, we have,
Degree measure ([tex]\theeta[/tex][tex]\alpha[/tex]) = 96° = 96[tex]\pi[/tex]/180
Radius (r) = 9cm
Length of arc (l) = ?
Now,
∝ = l /r
or, [tex]\frac{96\pi }{180}[/tex] =[tex]\frac{l}{9}[/tex]
or, l =[tex]\frac{(96\pi )(9)}{180}[/tex] =4.8[tex]\pi[/tex]cm

A:0 and 4,B:2,C:4,D:0.
Answer:
A. 0 and 4
Step-by-step explanation:
The x-intercepts are simply the values of x when y = 0. In other words it is the points where the line curve intercepts or cuts across the x-axis.
Form the graph given, we can see that at x = 0 and x = 4, the value of y = 0. Simply put, the curve cuts the x-axis at x = 0 and x = 4.
x-intercepts are 0 and 4.

Answer:
Length of mammoth's tusk in poster = 15.33
Step-by-step explanation:
Actual height of mammoth = 10 feet 5 inches = 126 inches
Height on the poster of mammoth = 14 inches
Actual length of mammoth's tusk = 11.5 feet = 138 inches
Length of mammoth's tusk in poster = x
126 : 14 :: 138 : x
Product of mean = product of extremes
x * 126 = 14 * 138
