Vinvika [58]

Answer: The number of yes votes = 1918.

Step-by-step explanation:

Given : The ratio of yes to no votes = 2:3

Then the ratio of yes to total votes = $\dfrac{2}{2+3}=\dfrac25$

Total votes = 4795

Number of yes votes = (ratio of yes to total votes) x (Total votes )

= $\dfrac{2}{5}\times4795=1918$

Hence, the number of yes votes = 1918.

An SRS of 100 flights of a large airline (airline 1) showed that 64 were on time. An SRS of 100 flights of another large airline

IRINA_888 [86]

Answer:

Option b) between 0.05 and 0.01.

Step-by-step explanation:

We are given the following in the question:

$x_1 = 64\\n_1 = 100\\x_2 = 80\\n_2 = 100$

Let $p_1$ and $p_2$ be the proportion of all parts from suppliers 1 and 2, respectively, that are defective.

$p_1 = \dfrac{x_1}{n_1} = \dfrac{64}{100} = 0.64\\\\p_2 = \dfrac{x_2}{n_2} = \dfrac{x_2}{n_2} = \dfrac{80}{100}= 0.8$

First, we design the null and the alternate hypothesis

$H_{0}: p_1 = p_2\\H_A: p_1 \neq p_2$

We use Two-tailed z test to perform this hypothesis.

Formula:

$\text{Pooled P} = \dfrac{x_1+x_2}{n_1+n_2}\\\\Q = 1 - P\\\\Z_{stat} = \dfrac{p_1-p_2}{\sqrt{PQ(\frac{1}{n_1} + \frac{1}{n_2})}}$

Putting all the values, we get,

$\text{Pooled P} = \dfrac{80+64}{100+100} = 0.72\\\\Q = 1 - 0.72 = 0.28\\\\Z_{stat} = \frac{0.64-0.8}{\sqrt{0.72\times 0.28(\frac{1}{100} + \frac{1}{100})}} = -2.5198$

Now, we calculate the p-value from the table at 0.05 significance level.

P-value = 0.01174

Since,

$0.05 > 0.01174 > 0.01$

Thus, the correct answer is

Option b) between 0.05 and 0.01.
