Question 1: In 1965, a newspaper carried a story about a high school student who reported getting 9207 heads and 8743 tails in 17,950 coin tosses. Is this a significant discrepancy from the null hypothesis H₀= 1/2.

Question 2: Jack Youden, a statistician at the National Bureau of Standards, contacted the student and asked him exactly how he performed the experiment. To save time the student tossed groups of five coins at a time, and a younger brother recorded the results, shown in the following table:

Number of Heads	Frequency
0	100
1	524
2	1080
3	1126
4	655
5	105

Are the data consistent at the 1% significance level with the hypothesis that all the coins are fair (p = 1/2)?
