Answer:
• (a)1320.5 thousand per year
,
• (b)f(x)=1320.5x+10602
,
• (c)f(7)=19846 thousand
Explanation:
Sales in the year 2009 = 10,602 thousand
Sales in the year 2013 = 15,884 thousand.
(a)Average rate of change (slope) from 2009 to 2013.
(b)If x is the number of years since 2009 and f(x) is the number of vehicles sold
When x=0, f(x)=10,602 thousand
The slope-intercept form of the equation of a line is: y=mx+b
The equation of the line through these two points is:
(c)Number of vehicles sold in 2016.
2016-2009=7
Therefore, when x=7
The number of vehicles sold, f(x) will be:
Answer:
b) B and D and c) A and C
Step-by-step explanation:
The hypotheses would be:
(Right tailed test at 5% level)
Sample proportions are
Sample A B C D
Success 31 34 27 38
Proportion p 0.775 0.85 0.675 0.95
Std error
(sqrtpq/n) 0.066 0.056 0.074 0.034
p diff
p-0.75 0.025 0.10 - 0.075 0.20
Z stat
p diff/SE 0.0757 1.77 1.01 5.80
p value 0.469 0.038 0.156 0.000001
we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.
b) Only B and D provide against the null. Because p <0.05
c) A and C provide no evidence for the alternative because p >0.05
