- The customer help center in your company receives calls from customers who need help with some of the customized software solutions your company provides. Your company claims that the average waiting time is 7 minutes at the busiest time, from 8 a.m. to 10 a.m., Monday through Thursday. One of your main clients has recently complained that every time she calls during the busy hours, the waiting time exceeds 7 minutes. You conduct a statistical study to determine the average waiting time with a sample of 35 calls for which you obtain an average waiting time of 8.15 minutes. If the population standard deviation is known to be 4.2 minutes, and a = 0.05, the p-value is approximately 0.05 0.025 ○ 0.053 ○ 0.10 ○ 0.026arrow_forwardThe procedures for doing hypothesis testing of proportions and hypothesis testing of means are similar, but what is one of the differences they have ?arrow_forwardThe p-value is the probability of a statistic being at most as extreme as the observed value when Ho is false. the probability that the alternative hypothesis is true. O the probability that the null hypothesis is true. O the probability of a statistic being at most as extreme as the observed value when Ho is true. O the probability of a statistic being at least as extreme as the observed value when Ho is true.arrow_forward
