Allison didn't drive at constant rate.

Step-by-step explanation:

We need to identify if time and distance have proportional relationship

A relationship is proportional if y/x = k

If x = time and y = distance and y/x is equal to constant then they have proportional relationship.

if x= 1, y=65 then k is:

y/x = 65/1 = 65

if x=2, y =120 then k is:

y/x = 120/2 = 60

if x=3,y=195 then k is:

y/x = 195/3 = 65

if x=4,y=220 then k is:

y/x = 220/4 = 55

if x=5,y=300 then k is:

y/x = 300/5 = 60

Since, y/x ≠ k i.e the ratio of y and x doesn't equal to the constant rate, so time and distance doesn't have proportional relationship.

So, Allison didn't drive at constant rate.

A survey of 80 randomly selected companies asked them to report the annual income of their presidents. Assuming that incomes are

Artyom0805 [142]

Answer:

The 90% confidence interval estimate of the mean annual income of all company presidents is ($579,545, $590,580).

Step-by-step explanation:

The information provided is:

$n=80\\\sigma=30,000\\\bar x=585062.50\\\text{Confidence level} = 90\%$

The critical value of <em>z</em> for 90% confidence level is, 1.645.

Compute the 90% confidence interval estimate of the mean annual income of all company presidents as follows:

$CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\\\\=585062.50\pm 1.645\times\frac{30000}{\sqrt{80}}\\\\=585062.50\pm5517.50\\\\=(579545, 590580)$

Thus, the 90% confidence interval estimate of the mean annual income of all company presidents is ($579,545, $590,580).

This interval implies that there is 90% probability that the true mean annual income of all company presidents is within this interval.
