The property is 109 because its 109
Answer:
A. No, the hypothesis test was conducted correctly, and the correct conclusion was made.
Step-by-step explanation:
Given that the head of institutional research at a university believed that the mean age of full-time students was declining. In 1995,the mean age of a full-time student was known to be 27.4 years.
For this he has recorded all 4934 students and got average as 27.1 years
This is very much perfect because the question is about the mean age of a full time student. when all full time students in the university are taken into account and mean arrived this is a reliable procedure.
The hypothesis also is right as this is left tailed test.
Since p =0.002<0.05 he rejected null hypothesis.
Conclusion is the mean age did decline. Everything is right.
A. No, the hypothesis test was conducted correctly, and the correct conclusion was made.
The expected value of the outcome of the bid is $0.18
So let's start by counting how many bids are placed up to a total of 160.
100*160 = 16000.
What will be your arbitrary bid? As each bid has an equal chance of success, the average of all bids is used. (One cent plus 160 dollars) / 2 = 80 dollars (rounded)
Your odds of winning are 1/16000 (1 bid out of 16000).
If you win, your profit is 1920 ($2000 minus $80.00).
1920/16000 is $0.12
Your cost to enter the auction is $1, and your average winning offer is $0.12.
The result is $0.18 (0.12-1=-0.88).
Thus the expected value of the outcome of the bid is $0.18
