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:
The correct answer is option D. 48
Step-by-step explanation:
From the figure we can see that, some right angled triangles.
<u>To find the measure of LP</u>
Consider the right angled triangle LPT,
LT is the hypotenuse, LP = 50 units (given)
PT = QT = RT = 14 units
From figure we get,
LP² + PT² = LT²²
LP² = LT² - PT²
= 50² - 14²
= 2500 - 196
= 2304
LP =√2304
= 48
The correct answer is option D. 48
Answer:
The mode if 5, because 5 Acres 8 times, which is more than any other occurs more than once. The median 6, and this is because when you line up the numbers in Order in Cross I'm off to fly in the middle number, it is 6. I rounded it to the mean in about 6.4. I got this by adding all the numbers up, we're doing 12 + 40 + 18 +, Eta, and got the total of 165. Cuz there is a total of 26 data points, I divided those numbers and God 6.3461, which ends up rounding to 6.4
