A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the
Svetradugi [14.3K]

Answer:

The probability that the sample proportion will be less than 0.05 is 0.80511.

Step-by-step explanation:

We are given that a courier service company wishes to estimate the proportion of people in various states that will use its services.

Suppose the true proportion is 0.04 and 349 are sampled.

<u><em>Let </em></u>\hat p<u><em> = sample proportion</em></u>

The z score probability distribution for sample proportion is given by;

                                  Z = \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }  ~ N(0,1)

where, \hat p = sample proportion

           n = sample size = 349

           p = population proportion = 0.04

Now, the probability that the sample proportion will be less than 0.05 is given by = P( \hat p < 0.05)

         P( \hat p < 0.05) = P( \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } } < \frac{0.05-0.04}{\sqrt{\frac{0.05(1-0.05)}{349} } } ) = P(Z < 0.86) = 0.80511

<em>The above probability is calculated by looking at the value of x = 0.86 from the z table which has an area of 0.80511.</em>

Hence, the probability that the sample proportion will be less than 0.05 is 0.80511.

Find the slope for the following pair of points:<br><br> (-14,3) and (-3, 0)
insens350 [35]

Answer:

slope = - \frac{3}{11}

Step-by-step explanation:

calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 14, 3 ) and (x₂, y₂ ) = (- 3, 0 )

m = \frac{0-3}{-3-(-14)} = \frac{-3}{-3+14} = - \frac{3}{11}
