Tennis players often spin a racket to decide who serves first. The spun racket can land with the manufacturer's label facing up or down. A reasonable question to investigate is whether a spun tennis racket is equally likely to land with the label facing up or down. (If the spun racket is equally likely to land with the label facing in either direction, we say that the spinning process is fair.) Suppose that you gather data by spinning your tennis racket 60 times, each time recording whether it lands with the label facing up or down. From this you calculate the proportion of times the racket lands with the label facing up. Suppose that the spun racquet lands with the label facing up 26 times out of 60. Does this result constitute strong evidence against believing that the spinning process is fair
