Answer:
If the proportions of all people who carry the trait are the same for both populations, the probability of observing a sample difference of at least 0.22 is 0.03
Step-by-step explanation:
Given the hypothesis :
H0 : pW = pX
Ha : pW > pX
W - X = 0.22
Pvalue = 0.03
Since the Pvalue gives the probability of obtaining a value or result figure which is atleast as extreme as the observed value. The observed value here is 0.22 resulting from the difference in W and X (W - X).
This can thus be interpreted to mean ; going by the Null (difference between W and X) ; the probability of obtaining a value of atleast 0.22 as difference is 0.03
So we replace x with 3. f(3)=3^2-2(3)+6. and f(3)=9-6+6=9. and the answer is d which is 9.
Answer:
Step-by-step explanation:
There are 100 pence to the British note.
Using that, we can multiply the 5 notes by 100 to get 500 pence.
If each pen is 15 pence, we can just divide 500 by 15 to get about 33 pens he can buy, meaning that he has just enough money for 32 pens and some change because 33 is greater than 32.
