Answer:
A) Increase the significance level to increase the probability of a Type I error
Step-by-step explanation:
According to the information of the problem we can say that the researchers have the difficulty with a test that is evaluating a machine, which works well but the test does not get to verify this information correctly, we have that the null hypothesis is that the new machine does not improve precision, so the risk of the researchers is to accept the hypothesis when it is false, what is called type II error, to avoid this, the level of significance should be increased, which in turn would increase the probability of type I error. , so the correct answer is A.
Answer:
y=2x+14
Step-by-step explanation:
y-y=m(x-x1)
y-6=2(x-(-4))
y-6=2x+8
+6 +6
y=2x+14
When solving problems like these, the easiest thing to do is either turn both fractions into decimals or into fractions with a common denominator.
So 3/4 = 0.75 OR 9/12
And 2/3 = .666 OR 8/12
In solving the actual question, you're looking for the store that gives the better deal, meaning that they sell MORE apples for LESS.
The first store sells 9/12 of a bushel for $9 and the second store sells 8/12 of a bushel for $8.
The answer is the first store which sells 3/4 of a bushel for $9.

Answer: a) 0.8665
b) 0.8190
Step-by-step explanation:
Given : The partial pressure of oxygen PaO2 is a measure ofthe amount of oxygen in the blood. Assume that the distribution ofPaO2 levels among newborns has a
38 mmHg and
9 mmHg.
If we take a random sample n= 25 newborns, then using formula
, we have
At x= 36

At x= 41

Using table for z-values, the probability that the sample mean will be greater than 36 :

The probability that the sample mean will be between 36 and 41 :-

(x+2)/6 = 2/5
(x+2)5 = 12 <-- Cross multiply
5x = 6 <-- Transpose the 2.
6/5 = x
