A manufacturer makes ball bearings that have a target diameter of 5 mm. Quality control engineers sample ball bearings from a batch to test the hypotheses H 0 : mu=5 mm vs. H a : mu ne5 mi , where u is the true mean diameter of the ball bearings in that batch. Suppose that H 0 is actually true. Which situation below would have the lowest probability of a Type I error?
Answer: n=30 the other one is 0.01 !
Step-by-step explanation:

The situation that would have the lowest probability of a Type I error is the one with the smallest significance level (α).
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
In hypothesis testing,
A Type I error occurs when we reject the null hypothesis (H0) when it is actually true.
The probability of a Type I error is denoted by the symbol alpha (α) and is usually set to a small value, such as 0.05 or 0.01.
Now,
To minimize the probability of a Type I error, we want to choose a significance level (α) that is small.
This means that we are willing to accept a lower probability of detecting a difference when one actually exists (i.e., a higher probability of a Type II error).
For example,
If we set α = 0.01, we are saying that we are willing to accept only a 1% chance of incorrectly rejecting the null hypothesis (H0) when it is actually true. This would result in a very small probability of a Type I error.
Therefore,
The situation that would have the lowest probability of a Type I error is the one with the smallest significance level (α).

Answer:
240 people
Step-by-step explanation:
[tex]\frac{60}{25} =\frac{x}{100}[/tex] (x represents people)
60×100= 6000 , 25 × [tex]x[/tex] = 25[tex]x[/tex]

What is the actual area of the entire floor? Explain how you found the area. length 4.0 in. Study Living Room 8.0 in. 2.0 in. Foyer width
Answer:
Part A= 19.2 Part B= 27.2
Step-by-step explanation:
4+8=12 divided by 1.25 equals 19.2
Width= 4+6=10 divided by 1.25=8
19.2+8= 27.2 is the total area
Hope this is right (:
Answer:
A. 19.2 Feet
B. 307.2 Feet
Step-by-step explanation:
A. First you divide 2 feet by 1.25 inches to figure out how much feet per inch.
2/1.25=1.6 feet
Meaning that 1 inch is 1.6 feet or 1 inch=1.6 feet
After that you add the length of 4 inches and 8 inches which equals 12 inches.
4+8=12 inches
After that you multiply 12 by 1.6
12*1.6=19.2
Meaning that the actual length is 19.2 feet
B. Once you find the length you add 4 inches and 6 inches which equals 10 inches.
Multiply 10 by 1.6
10*1.6=16 feet
After that to find the area you multiply 16 and 19.2.
16*19.2=307.2 feet

Find the volume of the cone. Round your answer to the nearest tenth if necessary. Use 3.14 for it.
8 ft
6 ft
Answer:
75.4 ft³
Step-by-step explanation:
Volume of a cone = πr²h/3
π = 3.14
radius, r = diameter / 2
= 6ft/2
= 3 ft
Height, h = 8 ft
Volume of a cone = πr²h/3
= (3.14 * (3)² * 8) / 3
= (3.14 * 9 * 8) / 3
= 226.08 / 3
= 75.36
Volume of a cone = 75.36 ft³
Approximately to the nearest tenth = 75.4 ft³

An angle measures 26° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
103 & 77 degrees
Step-by-step explanation:
Supplements add up to 180 degrees.
I started at 90 & did:
90 + 13 = 103
(Because 13 * 2 is 26, but if you subtract 26 then the supplement will be 52 away & not 26)
180 - 103 = 77
103 - 77 = 26
Hope this helped. :)
