It is hypothesized that the average number of Girl Scout cookie boxes sold per day at a local mall is 200. To test this, 25 days were randomly examined during days Girl Scout cookies were being sold. The resulting sample mean and standard deviation were 180 and 40, respectively. Provide a test at the 0.05 level of significance. Assume a normal distribution.

A random sample of 15 students showed that their average fear of math was 84.8 on a 1-100 scale, with a standard deviation of 2.7. At the α = .01 significance level, test the claim that the average fear of math of all students is below 85 on this scale. b) Suppose now the same mean and standard deviation were found in a random sample of 10000 students. Again, at the α = .01 significance level, test the claim that...

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 417 gram setting. Based on a 10 bag sample where the mean is 427 grams and the standard deviation is 17 , is there sufficient evidence at the 0.05 0.05 level that the bags are underfilled or overfilled? Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses. 2. test statistic 3. p-value 4. level...

HT Mean: A Packaging Company produces boxes out of cardboard and has a specified weight of 35 oz. It is known that the weight of a box is normally distributed with standard deviation 1.3 oz. A random sample of 36 boxes yielded a sample mean of 35.5 oz. At 5% level of significance, test the claim that the mean weight of a box is 35 oz or is there significant evidence that the mean weight is greater than 35 oz....

A simple random sample of 70 customers is taken from a customer information file and the average age is 36. The population standard deviation σ is unknown. Instead the sample standard deviation s is also calculated from the sample and is found to be 4.5. (6 points) Test the hypothesis that the population mean age is greater than 33 using the critical value approach and a 0.05 level of significance. Test the hypothesis that the population mean age is less...
