Distributive Property:
The distributive property tells us how to solve expressions in the form of a(b + c).
In this question we have to find two numbers that add up to give 105,
Now replacing 105 by 100 + 5, rewriting the expression as :
distributing 327 over 100 and 5
here a=327, b =100 and c=5
Answer:
Answer:
Paedtricians claim isn't true.
Step-by-step explanation:
The hypothesis :
H0 : σ = 7
H0 : σ > 7
The test statistic ; χ² :
χ² = [(n - 1) * s²] ÷ σ²
n = 25 ; s = 4.3, σ = 7
χ² = [(25 - 1) * 4.3²] ÷ 7²
χ² = [(24 * 4.3²] ÷ 49
χ² = 443.76 / 49
χ² = 9.056
At α = 0.01 ; critical value = 42.980
Since critical value > test statistic, we fail to reject the null, H0.
