Answer:

The answer is "Option b".

Step-by-step explanation:

In the given question, 1000 ticket were sold for \$1 and the owner who receives tickets which are  randomly chosen that wins \$50.

Net\  profit = 1000\times 1-1\timesv 50 = \$950\\\\Net \ profit \ for\  ticket = \frac{\$950}{1000} = \$0.95

The probability in which each ticket owners win = 0.001

therefore the ticket owner net profit = = -1+0.001\times 50 = -0.95\\\\

WARRIOR [948]

Since the p-value of the test is of 0.00001 < 0.01, these results have statistical significance.

<h3>What is the relation between the p-value and the conclusion of the test hypothesis?</h3>

Depends on if the p-value is less or more than the significance level:

  • If it is more, the null hypothesis is not rejected, which means that the results do not have statistical significance.
  • If it is less, it is rejected, which means that the results have statistical significance.

In this problem, the probability is the p-value, hence since the p-value of the test is of 0.00001 < 0.01, these results have statistical significance.

Three consecutive numbers have a sum of 366, what is the largest consecutive number of the three?
Llana [10]

Answer: 123

Step-by-step explanation: TO solve problems like this, you should assign a variable to the lowest number, lets just say n. From here, since we know the numbers are consecutive, we can see that the numbers are n, n+1, and n+2. Therefore:

n(first number) + (n+1)(second number) +(n+2) (3rd number) =366

>n+n+1+n+2=366

3n+3=366

3n=363

n=121

n+2=123
