Answer:
1. The chi-squared statistic = 10.36
The degrees of freedom = 17
The p-value for the test = 0.89
2. The range of the p-value from the Chi squared table = 0.75 < p-value < 0.90
Step-by-step explanation:
1. The Chi squared test is given as follows;
Therefore,
UTI No UTI % Total
Cranberry juice 8 42 84 50
Lactobacillus 19 30 61 49
Control 18 30 60 50
The chi-squared statistic is given as follows;
The chi-squared statistic = 10.36
The degrees of freedom, df = 18 - 1 = 17 since the all of the expected count have a minimum value of 18
With the aid of the calculator we find the p value as p as follows;
The p-value for the test = 0.89
2. The range of the p-value from the Chi squared table is given as follows;
0.75 < p-value < 0.90.
Answer:
<u>310</u> tickets were sold in advance before school pay and <u>340</u> door tickets were sold in advance.
Step-by-step explanation:
Given:
Let number of tickets sold in advance be 'x'.
Cost of advance ticket = $3
Cost of door tickets = $5
Also given:
Thirty more tickets were sold at door in advance
Hence number of door tickets sold =
Total Money Collected = $2630
Now we can say that Total Money Collected is equal to sum of number of tickets sold in advance multiplied by Cost of advance ticket and number of door tickets sold multiplied by Cost of door tickets.
Framing in equation form we get;
Solving the equation to find the value of x we get;
Combining the like terms we get;
Now Dividing 8 on both side using division property we get;
Substituting the value of x to find number of door tickets been sold.
number of door tickets sold =
Hence, <u>310</u> tickets were sold in advance before school pay and <u>340</u> door tickets were sold in advance.
