A random sample of 84 trials yields 79successes. Use a = 0.01.1. To confirm that the sample is large enough, there must be at least 5 successes and 5 failures. We areokay here, since there are 79 successes andfailures.The hypotheses are:Ο H0:μ Σ 0.85 ; Ha : μ < 0.85O Ho:p = 0.85; Ha:p# 0.85Ο Ho:μ< 0.85; Ha : μ > 0.85O Ho:u = 0.85; Ha:µ 0.85O Ho:p > 0.85; Ha:p < 0.85O Ho:p <0.85; Ha:p > 0.852.
