Answer: The correct option is
(B) f(x) is a very large positive number.
Step-by-step explanation: We are given the graph of a function f(x) as shown in the figure.
We are to check what happens to the f(x) when x is a small positive integer.
From the graph, we see that
when x is approaching to 0 from left hand side, then the value of f(x) is approaching to negative infinity.
And,
when x is approaching to 0 from right hand side, then the value of f(x) is approaching to positive infinity.
So, when x is a very smell positive integer, then y is approaching to positive infinity.
That is, the value of f(x) is a very large positive number.
Option (B) is CORRECT.
Answer:
See explanation below
Step-by-step explanation:
Here, a director of manufacturing must convince management that a proposed manufacturing method reduces costs before the new method can be implemented. The current production method operates with a mean cost of $220 per hour.
a) The alternative and null hypotheses would be:
H0: μ ≥ 220
Ha: μ < 220
b) Comment on the conclusion when H0 cannot be rejected:
When we fail to reject the null hypothesis H0, there is not enough evidence to conclude that the mean cost can be reduced from $220. Therefore the manager's proposed method cannot be implemented.
c) Comment on the conclusion when H0 can be rejected:
When the null hypothesis, H0 is rejected, there is enough evidence to conclude that the mean cost can be reduced from from $220. Therefore the manager's proposed method can be implemented.
