At a plant that manufactures bars of steel, a machine is used to cut the bars to specific lengths. The machine has a dial that sets the length of the bars to be cut. However, the dial is currently out of alignment and the plant manager is collecting data to assess the situation. The following table shows 8 trials at different dial settings along with the actual output length of the bars that were cut. All measurements are in millimeters

Answers

Answer 1

The regression line that can be formed from the information about the plant that manufactures bars of steel will be 2.2043 + 1.0068x.

What is a regression line?

It should be noted that a regression line simply means the line that displays the connection between the scattered points in a data set.

In this case, the regression line that can be formed from the complete binformation will be:

b0 = y - b1x

= 8.3 - 1.0068(80.25)

= 8.3 - 80.7957

= 2.2043

Therefore, the regression line is 2.2043 + 1.0068x.

A data set includes body temperatures of healthy adult humans having a mean of f and a standard deviation of f. construct a ​% confidence interval estimate of the mean body temperature of all healthy humans. what does the sample suggest about the use of 98.6f as the mean body​ temperature?

Answers

What the sample suggests is that; the mean body temperature couldvery possibly bevery possibly be 98.6 °F.

What is the Confidence Interval?

For a 99% Confidence Interval and DF = 103 - 1 = 102, the value of z = 2.33.

The formula for confidence interval is;

CI = x⁻ ± z(σ/√n))

We are given;

Sample mean; x⁻ = 98.9

standard deviation; σ = 0.67

sample size; n = 103

Thus the confidence Interval is;

CI = [98.9 - 2.33(0.67/√103)], [98.9 + 2.33(0.67/√103)]

CI = (98.9 - 0.154, 98.5 + 0.154)

CI = (98.36, 98.64)

Thus, 98.6 is contained within the 99% CI,and so we can conclude that the the mean body temperature could very possibly bevery possibly be 98.6 °F.

What is the variance of the data? 0.0625 0.25 0.5 1.5

Answers

The variance of the dataset is the square of their standard deviation

The variance of the dataset is 0.307

How to determine the variance?

The dataset is given as;

0.0625 0.25 0.5 1.5

Calculate the mean using:

μ = Sum/Count

So, we have:

μ = (0.0625 + 0.25 + 0.5 + 1.5)/4

Evaluate

μ = 0.578125

The variance is then calculated using:

[tex]\sigma^2 = \frac{\sum(x - \mu)^2}{n}[/tex]

So, we have:

[tex]\sigma^2[/tex] = [(0.0625 - 0.578125)^2 + (0.25 - 0.5781250^2 + (0.5 - 0.578125)^2 + (1.5 - 0.578125)^2]/4

Evaluate

[tex]\sigma^2[/tex] = 1.2294921875/4

Divide

[tex]\sigma^2[/tex] = 0.30737304687

Approximate

[tex]\sigma^2[/tex] = 0.307

Hence, the variance of the dataset is 0.307

Volume is a three-dimensional scalar quantity. The company should choose the cylinder because it has approximately 11.6in³ less wasted space than the prism.

What is volume?

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the two balls with a radius of 1.5 inches is,

[tex]=2 \times \dfrac43 \times \pi r^3 \\\\= 28.2743\rm\ in^3[/tex]

The Volume of the prism with dimensions 6in × 3in × 3in are,

Volume of the prism = 6in × 3in × 3in = 54 in³

The volume of the cylindrical box with a radius of 1.5 in and a height of 6 inches is,

Volume of Cylinder = πr²h = π × (1.5)² × 6 = 42.4115 in³

Wasted volume in Prism, when two balls are inside,

Wasted Volume = 54in³ - 28.27in³ = 25.72566 in³

Wasted Volume in Cylinder, when two balls are inside,

Wasted Volume = 42.4115in³ - 28.27in³ = 14.137 in³

The difference in the waste volume of prism and cylinder,

Difference = 25.72566in³ - 14.137in³ = 11.6in³

What additional measurements must be made to determine the momentum of block 2 after the collision?

Answers

The additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1

What is momentum?

Momentum can be defined as a scalar quantity that involves the multiplication of the mass of an object by its velocity.

In Physics, the momentum of an object such as a block, is calculated by using this formula;

Momentum = mass × velocity

In conclusion, we can deduce that the additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1.
