Question

Perform these hypothesis tests. Show the formulas for the test statistics and what numbers go into them. Clearly show your decision, write it in words, and be sure to write out your null and alternative hypotheses. Researchers wanted to investigate whether a spun tennis racket is equally likely to land with the label facing up or down. They spin a racket 120 times, and in 50 of the spins, the racket lands what they label as “up.”
