A random sample of 54 students from Cabrillo College are selected from a normal population with mu equal to 20 and sigma equal to 5. After a treatment is administered to the students, the researcher calculated the sample mean to be 21. Is there enough evidence to conclude that the treatment had an effect at the 5% significance level?
In step three, can we use the Critical Value Method?
(a)Don't know
(b)Cannot Determine
(c)No
(d)Yes
1. What is the standardized test statistic?
t = ___.
2. What is/are the critical value(s)?
Arsenic-based additives in chicken feed have been banned by the European Union. Ifa restaurant chain finds significant evidence that the mean arsenic level of theirchickens is above 80 ppb (parts per billion), the chain will stop using that supplier ofchicken meat. The hypotheses are:
H 0 : µ = 80H 1 : µ > 80
where µ represents the mean arsenic level in all chicken meat from that supplier.Samples from two different suppliers are analyzed, and the resulting p-values aregiven:
Sample from Supplier A: p-value is 0.0003Sample from Supplier B: p-value is 0.3500
a) Interpret each p-value in terms of the probability of the results happening byrandom chance.
b) Which p-value shows stronger evidence for the alternative hypothesis?
c) Which supplier, A or B, should the chain get chickens from in order to avoid toohigh a level of arsenic?
