Answer:
He could increase the sample size
Step-by-step explanation:
In hypothesis testing, the error associated with the test is affected by a number of factors. The first factor is the level of significance, alpha. This is the probability of type 1 error. The probability of rejecting the null hypothesis when it is indeed true.
The second factor is the size of the sample used. The larger the sample, the smaller the error since the characteristics of the sample will be closer to those of the entire population on which inference is being made
I think the answer is 2.25 or 2 and 1/4.
You divide 3/4 by 1/3 and get 2.25 or 2 and 1/4.
I don't know if this is right, I hope it is, have a good day. c;
Answer:
120 On edge i got it right
Step-by-step explanation:
Answer:
15 m
Step-by-step explanation:
Height of buiding h= 9m
Lenght from building l= 12m
let the length of the rope be x=???
Applying Pythagoras theorem
x^2=h^2+l^2
x^2= 9^2+12^2
x^2= 81+144
x^2=225
square both sides
x=√225
x=15 m
Hence the length of the rope is 15 m
