The standard deviation for this survey group was 4 minutes. Based on this data, they calculate test statistic 0.901 and the p-value 0.385. i) What can be conduded at the o = 0.001 level of significance? Based on this, we should Select an answer | the null hypothesis. ii) Thus, the final condusion is that ... O The data suggest that the population mean amount of time to make a pizza at Super Fast Pizza is not significantly different from 19 at o = 0.001, so there is statistically insignificant evidence to condude that the population mean amount of time to make a pizza at Super Fast Pizza is different from 19. O The data suggest the populaton mean is significantly different from 19 at or = 0.001, so there is statistically significant evidence to conclude that the population mean amount of time to make a pizza at Super Fast Pizza is different from 19. O The data suggest the population mean is not significantly different from 19 at or = 0.001, so there is statistically insignificant evidence to conclude that the population mean amount of time to make a pizza at Super Fast Pizza is equal to 19
