Answer: The proportion of new car buyers that trade in their old car has statistically significantly decreased.
Step-by-step explanation:
Since we have given that
p = 48% = 0.48
n = 115
x = 46
So,
So, hypothesis would be
So, test value would be
At 10% level of significance, critical value would be
z= 1.28
Since 1.28 < 1.72
So, we will reject the null hypothesis.
Hence, the proportion of new car buyers that trade in their old car has statistically significantly decreased.
In two weeks he will lose 3 pounds
In 8.5 weeks he will lose 12.75 pounds
p= w(-1.5)
The range of the function is f(x) <= 4
<h3>How to determine the range?</h3>
The attached graph is the missing piece in the question
The function f(x) is given as:
- 2 lines connected
- Horizontal line y = 4 to (0, 4)
- Another line from (0, 4) through (4, 0)
The above means that, the value of the function do not exceed y = 4
Hence, the range of the function is f(x) <= 4
