Statistics

In a 17 month period the powerball was drawn from a collectionof 35 balls numbered 1-35. Total of 150 drawings were made. For thepurpose of this exercise we grouped numbers into five categories.test the hypothesis that each of the categories is equally likely.Use the 0.025 level of signifigance and the critical value methodwith the table.

Category:|1-7| |8-14| |15-21| |22-28| |29-35|

Observed: |21 | 35 | | 33 | | 27 | | 34 |

Expected frequencies for each category????

1)What are expected frequencies?

2)Compute the value of x^2. Round the answer to three decimalplaces

3)How many degrees of freedom are there?

4)State the null and alternate hypotheses

H0= p1=p2=p3=p4=p5= _____

Some or all of the actual probabilities (differ or ____) fromthe specifies by H0

5)Find the critical value. Round the answer to three decimalplaces.

6)determine whether to reject H0

7)State a conclusion

There (is or is not) enough evidence to conclude that thedistribution differs from what was expected.
