Question 1 of 37 sigma = 0.05ml A company manufactures U - 100 insulin syringes designed to contain 1 milliliter ( ml ) of a solution containing insulin . The actual distribution of solution volumes in these syringes is Normal , with mean and standard deviation . We randomly select 8 syringes , measure the volume of solution in each , and ask if the resulting data give evidence that the true population mean solution volume is not 1 ml . The software output contains results from a one - sample z test on the data collected .

A company manufactures U-100 insulin syringes designed to contain 1 milliliter (ml) of a solution containing insulin. The actual distribution of solution volumes in these syringes is Normal, with mean w and standard deviation = 0,05 ml. We randomly select 8 syringes, measure the volume of solution in each, and ask if the resulting data give evidence that the true population mean solution volume is not I ml. The software output contains results from a one-sample z test on the data collected. Variable N Mean StDev SE Mean 95% CI Z P volumes 8 1.0175 0.0320 0.0177 (0.9829, 1.8521) 0.99 0.322 Using a significance level of 0.05, what should you conclude? There is significant evidence that the true population mean volume is not I ml. The true population mean volume is proven to be I ml There is not enough evidence to say that the true population mean volume is not I ml. There is significant evidence that the true population mean volume is 1 ml. 8:41 PM
