I claim that my soda machine dispenses on average more than 12 ounces of soda. Test this claim at a significance level of a=0.05, using the following data: n=81, average=12.2 oz and s=2.4. What is the p-value of the Z test? do not round
Homework Answers
since population standard deviation is not known we cannot use z test but we can use t test because we have sample standard deviation value,
p value = p(t>0.75)@df = 81-1=80 = 0.2277

Workers at a certain soda drink factory collected on the volumes (in ounces) of a simple random sample of 22 cans of the soda drink those volumes have a mean of 12.9 oz and a standard deviation of 0.14 oz and they appear to be from a normally distributed population if the workers want to fill in process to work so that almost all the cans have volumes between 11. 95 oz and 12. 59 oz the range rule of...

Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 22 cans of the soda drink. Those volumes have a mean 12.19 oz and a standard deviation of 0.12 oz, and they appear to be from a normally distributed population. If the workers want the filling process to work so that almost cans have volumes between 11.89 oz and 12.57 oz, the range rule of thumb can be used to...

A machine in the lodge at a ski resort dispenses a hot chocolate drink. The average cup of hot chocolate is supposed to contain u = 8 ounces. We may assume that x follows a normal distribution with standard deviation r = 0.3 ounces. A random sample of 16 cups of hot chocolate from this machine had a mean content of x bar = 7.5 ounces. Use a a = 0.05 level of significance and test whether the mean amount...
