Question 1 12 pts Part 1 Q1) One bottle of COVIDI'? vaccine has a mean volume of 1100 microliter. The lling machine has a standard deviation of 54 microliters. Assume that the volume of the vaccine has a normal distribution. Q11) If 1000 microiiter is the required dosage, what is the probability that a person would get less than the required dosage? Q12} You randomly select 30 bottles and calculate the mean volume of the vaccine. If you create hypothesis to test that the machine is lling the vaccine bottle correctly or not. What would be the sign of your null hypothesis? A_: 3.3;: cg 0.: E. Type _ of the choice you answer: Q13) To test that the machine is lling the vaccine bottle correctly or not, you randomly select 30 bottles and the mean volume is 1108 microliter. If alpha is 0.04, what would be the conclusion of the hypothesis testing? A. Reject the nuli hypothesis because the test statistic is greater than the right critical value 3. Cannot reject the null hypothesis because the test statistic is less than the left critical value C. Cannot reject the null hypothesis because the test statistic is greater than the right critical value D. Cannot reject the null hypothesis because the test statistic is less than the right critical value E. Reject the nuli hypothesis because the test statistic is in tween the two critical values F. Reject the nuli hypothesis because the test statistic is less than the ieft critical value Type m of the choice you answer: Q2) A study:r shows that 75% of students prefer to learn on campus instead of online. If we randomly:r ask 36 students and ask about their preferences: Q21} What type of test statistic should we use to perform the hypothesis testing to test whether that the sampie come from the population with the parameter as motioned or not? A. ANOVA B. Levene test C. Tukey's range test D. Z_stat E. T_stat F. F_stat . | Type _ 0f the chOIce YOU answer: | Q22) If we want to prove that the sample comes from a population with the proportion greater than 0.75, what would be the sign of the null hypothesis? :I'IF'IPDP'P V/\\|V|/\\||'H\\ 2' 'U I'D O _,, 3' FD {1 3' 2 n I'D '
