A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the
kolbaska11 [484]

The probability that the sample proportion will be less than 0.04 is <u>0.8995</u> or <u>89.95%</u>.

The true proportion (p) is given to be 0.03.

Therefore, Mean (μ) = p = 0.03.

The standard error of sampling distribution can be calculated using the formula σ = √[{p(1 - p)}/n], where n, is the sample size, that is, n = 476.

Therefore, σ = √[{0.03(1 - 0. 03)}/476] = 0.00782.

Since, np = 14.28 and n(1 - p) = 461.72 are both greater than 5, we assume the sample is normally distributed.

Since, we are asked to find the probability that the sample proportion is <u>less than</u> 0.04, we using our calculator, enter as following:

Normalcdf(-100000000,0.04,0.03,0.00782), which gives us the value 0.8995 or 89.95%.

Thus, the probability that the sample proportion will be less than 0.04 is <u>0.8995</u> or 89.95%.

Please answer the circled questions below!
Anton [14]

Answer:

Step-by-step explanation:

1. The y-values in the table are constant, so the slope is 0. It is a horizontal line.

There is no x-intercept.

The y-intercept is (0, 1).

__

For lines in standard form, the intercepts can be found easily. The x-intercept is the value of x when y=0:

  ax +0 = c

  x = c/a . . . . x-intercept

Similarly, the y-intercept is the value of y when x=0:

  0 +by = c

  y = c/b

__

3. x-intercept = (-20/2, 0) = (-10, 0)

  y-intercept = (0, -20/-5) = (0, 4)

__

4. x-intercept = (-6/1, 0) = (-6, 0)

  y-intercept = (0, -6/-3) = (0, 2)

Plot these points and draw a line through them.

Step-by-step explanation:

you can easily add eqn 1 and 2 to get rid of the y term for 4th option and get rid of x term by addition as well for the 5th option

this is a topic on simultaneous equation. If you wish to explore more into this topic you can give me a follow on Instagram (learntionary) I'll be posting the notes for this topic and some other tips :)
