Answer:

90% confidence interval for the proportion of fans who bought food from the concession stand

(0.5603,0.6529)

Step-by-step explanation:

Step(i):-

Given sample size 'n' =300

Given data random sample of 300 attendees of a minor league baseball game, 182 said that they bought food from the concession stand.

Given sample proportion

$p^{-} = \frac{x}{n} = \frac{182}{300} =0.606$

level of significance = 90% or 0.10

Z₀.₁₀ = 1.645

90% confidence interval for the proportion is determined by

$(p^{-} - Z_{0.10}\sqrt{\frac{p(1-p)}{n} } , p^{-} +Z_{0.10}\sqrt{\frac{p(1-p)}{n} })$

$(0.6066 - 1.645\sqrt{\frac{0.6066(1-0.6066)}{300} } ,0.6066+1.645\sqrt{\frac{0.6066(1-0.6066)}{300} })$

(0.6066 - 0.0463 ,0.6066 + 0.0463)

(0.5603,0.6529)

final answer:-

90% confidence interval for the proportion of fans who bought food from the concession stand

(0.5603,0.6529)

Find the slope between the points (-3, -2) and (5, 4) (type in integer or reduced fraction you found only)

DiKsa [7]

Answer:

The slope is: $\frac{3}{4}$

Step-by-step explanation:

The equation for slope is:

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

Point 1: -3= $x_{1}$ , -2= $y_{1}$

Point 2: 5= $x_{2}$ , 4= $y_{2}$

4-(-2)=6

5- (-3)=8

6/8=3/4
