Since the data is insufficient. Let us denote that n1 = 100, n2 = 100X1 = 38. X2 = 40
So looking for the p value:
p = (38+ 40) / (100 + 100) = 0.39
z = (38/100 - 40/100)/√ (0.39*(1-0.39)*(1/100 + 1/100))= -0.2899
P-value = P (|z| > 0.2899) = 0.7718
Answer:253.33...
Step-by-step explanation:
Answer: x45=x45 cannot be greater because they're both equivalent to each other.
Step-by-step explanation:
8 friends share 3 cookies.
There are 3 cookies and 8 people.
We need to know how much cookie 1 friend gets.
1 friend gets 3/8 of a cookie.
There are 8 friends, so 8 x 3/8 = 3. The 8 friends will finish 3 cookies if they all have 3/8 of a cookie.
Each friend gets 3/8 of a cookie.
