The type of error that occurs if you fail to reject h0 when, in fact, it is not true is a type 2 error.
<h3>What is a type 2 error?</h3>
Type 2 error is when the null hypothesis is not rejected even though it is not false. Type 1 error is when the null hypothesis is rejected when it is true. A type 2 error leads to a false negative which is also known as an error of omission.

Answer:
40πcm
Step-by-step explanation:
circ = 2πr
if d = 40cm
r = 20cm
∴ c = 2×π×20
= 40πcm
= 125.66cm
Answer:
10y + 5
Step-by-step explanation:
You need to combine the Numbers with variables, and the numbers without variables need to be combined as well. Therefore, the answer is 10y +5.
Determine the mean ,median,modes ,IQR,and rage for the data 3,8,6,6,4,6,9,9,12
Verdich [7]
Mean:
Add all the numbers:
3 + 8 + 6 + 6 +4 + 6 + 9 + 9 + 12 = 63
There are 9 numbers.
63 / 9 = 7
Mean = 7
Median:
Order all the numbers:
3, 4, 6, 6, 6, 8, 9, 9, 12
The median is 6.
Mode:
The number that appears the most is 6.
The mode is 6.
Inter-Quartile Range :
Median of 2nd part = 9
Median of 1st part = 5
Subtract:
9 - 5 = 4
The IQR is 4.
Range:
The highest number is 12. The lowest is 3
Subtract:
12 - 3 = 9
The range is 9.
Hope this helped☺☺
