A pit crew claims that its mean pit stop time (for 4 new res and fuel) during an auto race is different than 13 seconds. A random sample of 40 pit stop times has a sample mean of 12.9 seconds and a population standard deviation of 0.3 second. Let a = 1%. Answers should be based on Rguroo-> mean inference -> one population output. a) The parameter of interest is [59ml V b) The null hypothesis Hg : p [SEW] V and the alternative hypothesis Haw, 75 13 c} The observed value is [59'9\"] V .E N Normaup = [59'9\"] V , 0'5 2 [Select] v ) d) The researcher can reject the null for (Tr: [59ml V and :17: > [59'9\"] V .
