Based on our analysis of our sample data, we are asked to perform a formal hypothesis test (test of significance) to examine if the average sodium content of all Jupiter Bars may actually be more than 96 milligrams.
1) Develop the correct null and alternative hypotheses using standard statistics symbols, using words, or using both.
2) Based on the context of the question we are investigating and the nature of our sample data:
a) Determine if using a normal distribution or a t distribution for the calculations is appropriate. Hint: consider the sample size.
b) State any assumptions or conditions regarding your sample and/or the population that are necessary for the test procedure you have chosen.
c) Using Statkey, find and record the correct p-value here to 4 decimal places, if the Z- or t- (whatever you chose in a) above) statistic = 3.209.
p value =
e) Using a significance level of 3% (alpha = 0.03), state clearly if you reject the null hypothesis or fail to reject the null hypothesis.
