Pasty has 5 identical discs in a bag with the number 1 written on one disc, the number 2 written on
another disc, the number 3 written on another disc, the number 4 written on another disc, and the
number 5 written on another disc. She picks a disc out of the bag at random, notes the number and
replaces it in the bag. She does this 200 times and notes her results in the table. Patsy wants to test
if her results follow a uniform distribution and she decides to use a chi-squared goodness of fit test
at the 10% significance level. Write down the null hypothesis and the alternative hypothesis.
