Answer:
Point estimate for the population standard deviation = 0.048
Step-by-step explanation:
We are given that a sample of 6 sewing needles is randomly selected and the following diameters are measured in millimeters;
X X - X bar
0.95 0.95 - 1.005 = -0.055 0.003025
0.99 0.99 - 1.005 = -0.015 0.000225
1.04 1.04 - 1.005 = 0.035 0.001225
0.95 0.95 - 1.005 = -0.055 0.003025
1.05 1.05 - 1.005 = 0.045 0.002025
1.05 1.05 - 1.005 = 0.045 <u> 0.002025 </u>
<u> Total = 0.01155 </u>
Firstly, mean of the data above, X bar = = = 1.005
Standard deviation of data, S.D. =
= = 0.048
Therefore, point estimate for the population standard deviation is 0.048 .
Answer:
Step-by-step explanation:
To solve the x-intercept, we plug in 0 for y and solve.
Answer:
2 can I have BRAINLIEST too
To make a box and whisker plot, first you write down all of the numbers from least to greatest.
0, 1, 3, 4, 7, 8, 10
The median is 4, so that’s the middle line of the plot.
So now we have:
0, 1, 3, [4,] 7, 8, 10
So next we have to find the 1st and 3rd interquartiles..
0, [1,] 3, [4,] 7, [8,] 10
Those are the next 2 points you put on the plot.
Lastly, the upper and lower extremes. These are the highest and lowest numbers in the data.
[0,] 1, 3, 4, 7, 8, [10]
These are the final points on the plot.
To make the box of a box-and-whisker plot, you plot the 3 Medians of the data: 1, 4, and 8, and connect those to make a box that has a line in the middle at 4.
Next, you plot the upper and lower extremes: 0 and 10, by making “whiskers” that connect to the box. So you draw a line from the extremes to the box.
