The Australian Journal of Health reported that in 2007 in Australia there were 10% of nursing home residents who were younger than 65 (Less than 65), 13% of residents who were between 65 and less than 75 (65 to less than 75), 32% who were between 75 and less than 84 (75 to less than 84) and 45% who were 84 and older (84+). The following data is from a recent survey of 6629 nursing home residents in Australia. Age

Current Number

Less than 65

398

65 to less than 75

663

75 to less than 84

2254

84 +

3314

At the 5% level of significance, has the age distribution of all nursing home residents changed since 2007?

In your answer include all steps necessary to perform the hypothesis test to answer this research question [including, but not limited to, calculation of the test statistic, the P-value, decision and conclusion].

i think the amount would be $140.62

b). 4320 have a nice day

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
