\bf \textit{volume of a sphere}\\\\
V=\cfrac{4\pi r^3}{3}~~
\begin{cases}
r=radius\\[-0.5em]
\hrulefill\\
V=972\pi \end{cases}\implies 972\pi =\cfrac{4\pi r^3}{3}\implies (3)972\pi =4\pi r^3
\\\\\\
\cfrac{(3)972\pi }{4\pi }=r^3\implies 729=r^3\implies \sqrt[3]{729}=r\implies 9=r

Carlton and Leon are expert bowlers. Seventy percent of Carlton's rolls are strikes, while 67% of Leon's rolls are strikes. Supp
IgorC [24]

Answer:

The probability that Leon strikes is greater than Carlton strike is 0.40905

Step-by-step explanation:

From the question, we have;

The percentage of Carlton's rolls are strikes, \hat p_1 = 70%

The number of games Carlton played, n₁ = 25

The percentage of Leon's rolls that are strikes, \hat p_2 = 67%

The number of games Leon played, n₂ = 25

Therefore, we have;

\hat p=\dfrac{k_1 + k_2}{n_1 + n_2}

Where;

k₁ = 0.7 × 25 = 17.5

k₂ = 0.67 × 25 = 16.75

\therefore \hat p=\dfrac{17.5 + 16.75}{25 + 25} = 0.685

The test statistic is given as follows;

Z=\dfrac{\hat{p}_1-\hat{p}_2}{\sqrt{\hat{p} \cdot (1-\hat{p})\cdot \left (\dfrac{1}{n_{1}}+\dfrac{1}{n_{2}}  \right )}}

Z=\dfrac{0.7-0.67}{\sqrt{0.685 \cdot (1-0.685)\cdot \left (\dfrac{1}{25}+\dfrac{1}{25}  \right )}} \approx 0.2283

From the z-table, we have;

The p-value for Carlton strikes is greater than Leon's strike = 0.59095

∴ The p-value for Leon strikes is greater than Carlton strike = 1 - 0.59095 = 0.40905

The probability that Leon strikes is greater than Carlton strike = 0.40905
