Um i think that you would have to do 50 ÷ 100 and then do 2 x (10 x 10) and i think that is how you would find your answer!
HOPE THIS WAS HELPFUL!
55:86
Step-by-step explanation:
86+55=123 so ratio is from girls to boys
Answer:
Of(7) = f(1) + 24
Step-by-step explanation:
Since this Arithmetic Sequence can be written recursively as a function, then we can write the whole sequence, by adding the common difference to the previous function. So writing it as an Arithmetic formula is (placing an example, with a common difference of 4 units):
Answer:
a. The value of Sample proportion(p) = 52 ÷ 420 = 0.124 ≈ 0.12
The formula for computing the test statistic is given by,
z = (p - P) ÷ σ
where, p is the sample proportion = 0.12
P is the hypothesized value of Population Proportion = 12.5% = 0.125
and σ is standard deviation
σ =
⇒ σ = 0.01
Putting all value in z. We get,
z = (0.12 - 0.125) ÷ 0.01
⇒ z = -0.5
Thus, the p-value at 5% level of significance foe one-tail test = 0.3085
Thus, we reject the null-hypothesis. Since, z-value > p-value.
