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

5+7=12 is the number of elements.
16,200/12=1350 value of each element.
5+1350=6,750 males.
7*1,350=9,450 females.
Proofs:
6,750+9,450=16,200
5/7=6,750/9,450
5*9,450=7*6,750

Which frequency table shows the test times (in minutes) for a reading test?
Naily [24]

In case the given numbers are :

81 63 61 58 72 70 79 68 82 64 54 82 72 63 64 76 57 64 73 58

we have :

50-59 , frequency is 4 (58, 54, 57, 58)

60 - 69, frequency is 7 ( 63, 61, 68, 64, 63, 64, 64)

70 - 79, frequency is 6 (72, 70, 79, 72, 76, 73)

80-89, frequency is 3 (81, 82, 82)

So correct option which matches the above data is option second.

Answer is table number two.
