Provate school in 2005
f(t)=85+18t

public school
g(t)=95+15t

graph
easy
replace g(t) and f(t) with y
y=18t+85
y=15t+95
input values for t and get values for y

y=18t+85
when t=0 y=85
when t=1 y=103
plot the oints (0,85) and (1,103)

y=15t+95
if t=0 then y=95
if t=1 then y=110
plot the points (0,95) and (1,110)

the easier way would just to be to solve the equatons but anyway
interscection point is (3 and 1/3,145)

so after 3 years (2008) it is about 145

The administration at Pierce College conducted a survey to determine the proportion of students who ride a bike to campus. Of th
8_murik_8 [283]

Answer:

The correct option is (D).

Step-by-step explanation:

To construct the (1 - <em>α</em>)% confidence interval for population proportion the distribution of proportions must be approximated by the normal distribution.

A Normal approximation to binomial can be applied to approximate the distribution of proportion <em>p</em>, if the following conditions are satisfied:

  • n\hat p \geq 10
  • n ( 1 - \hat p) \geq 10

In this case <em>p</em> is defined as the proportions of students who ride a bike to campus.

A sample of <em>n</em> = 125 students are selected. Of these 125 students <em>X</em> = 6 ride a bike to campus.

Compute the sample proportion as follows:

\hat p=\frac{X}{n}=\frac{6}{125}=0.048

Check whether the conditions of Normal approximation are satisfied:

n\hat p =125\times 0.048=610

Since n\hat p, the Normal approximation to Binomial cannot be applied.

Thus, the confidence interval cannot be used to estimate the proportion of all students who ride a bike to campus.

Thus, the correct option is (D).
