The mean is the average . the sum of number over the number of observation
x1=525
x2=487
s.d1=59.42
s.d2=51.74
n1=16
n2=12
Determine the hypothesis
u1≤u2
find the degree of freedom
25
p-value is the probability of obtaining the value of the test statistics. In the column of t-value in the row df=25
0.025<P<0.05
if the P value is actually less than or the same as the significant level, then the null hypothesis is rejected
P<0.05 rejected H
Answer:
Bola is 8 years old.
Step-by-step explanation:
Let Bola's age be x
Dada's age be y
Ayo's age be z
If the sum of ages of Bola, Dada and Ayo is 32 years, then;
x + y + z = 32
If they share a sum of money in ratio of their ages, then the ratio of their ages will be x : y : z
Also if Bola gets N400, Dada get-N400 and Ayo get N800, then the total amount of money shared will be expressed as:
T = 400 + 400 + 800
T = N1600
Next is to get the age of Bola
Substitute the required variables and values into the formula;
This shows that Bola is 8 years old
