sequals=12.612.6
million shares. Test the hypotheses by constructing a
9595%
confidence interval. Complete parts (a) through (c) below.
Answer: however, with the given options we can say that the correct option is "B", in which the value of the confidence interval is necessary to accept or reject the null hypothesis, we deduce that the value is not in the confidence interval so it must be rejected
