Answer: 9
Step-by-step explanation:
isn't it obvious
The first decimal place has the digit 0
the second decimal place has the digit 7
the third decimal place has the digit ....either 1 or 2.
this depends on the forth one, if it was 5 or higher, the third digit would be 2
since the fourth digit is 3, which is lower than 5, we don't have to change the third digit : it remains a "1"
so the answer is 0.071
Answer: The p-value is 0.154.
Step-by-step explanation:
Since we have given that
We claim that
Null hypothesis :
Alternate hypothesis :
Population mean = 20 hours
Sample mean = 18.5 hours
Sample standard deviation = 4.3 hours
Sample size n = 35
So, test statistic would be
So, the p value would be 0.154.
Hence, the p-value is 0.154.
<h2><u>
Answer and explanation:</u></h2>
Two events are said to be dependent on each other, if the outcome of the first thing affects the outcome of the second thing in such a way that the probability changes.
Here, the right answer will be = removing a marble from a bag, not putting it back, and then removing a second marble.
Explanation:
Lets suppose there were 10 marbles in the bag at the first place. Now, you removed one marble and did not put it back. So, remaining marbles will be 9. Now, if again you choose a marble, you have 9 marbles to choose from. We can see that probability changes with the event that occurred at first place.
So, this is the right answer.
Rest options are simultaneous one. They are not dependent in any way.
