Answer: A. 0.01
Step-by-step explanation:
Type I error are refered to as false positives and it means that when a statistically significant difference is validated by the researcher even though the results aren't statistically significant.
Type I error is when one rejects the null hypothesis even though it's actually true. In this case, the inspector rejects the hypothesis which was that the proportion of water that is contained the product is 0.5.
The probability of type 1 error will then be equal to the hypothesis level of significance and this will be 0.01.
Cereal A
10 ounces = $5.90
10/10 ounces = $5.90/10 .... divide both sides by 10
1 ounce = $0.59
1 ounce = 59 cents
----------
Cereal B
24 ounces = $6.48
24/24 ounces = $6.48/24 .... divide both sides by 24
1 ounce = $0.27
1 ounce = 27 cents
We see that Cereal B is the cheaper deal per ounce
---------
<h3>Answer: Cereal B is the better deal</h3>
Answer:
no solution exists:
Step-by-step explanation:
x²−1x+10=0
Step 1: Simplify both sides of the equation.
x²−x+10=0
Step 2: Subtract 10 from both sides.
x²−x+10−10=0−10
x²−x=−10
Step 3: The coefficient of -x is -1. Let b=-1.
Then we need to add (b/2)^2=1/4 to both sides to complete the square.
Add 1/4 to both sides.
x²−x+
1/4=−10+
1/4
x²−x+
1/4=−39
/4
Step 4: Factor left side.
(x -1/2)² = −39
/4
Step 5: Take square root.
x −1
/2 =±√
−39
/4
Step 6: Add 1/2 to both sides.
x =−1/2 + 1/2 = 1/2 ±√
-39/4
x = 1/2 ±√
-39/4
No real solutions.
Answer:
Step-by-step explanation:
For this case we can define the random variable of interest as: "The nicotine content in a single cigarette " and for this case we know the following parameters:
And for this case we select a sample size of n =100 and we want to find the following probability:
And for this case we can use the z score formula given by:
And replacing we got:
And we can find the required probability with the normal standard table and we got:
