In fiscal 1996, the U.S. Agency for International Development provided 238,300 metric tons of corn soy blend (CSB) for development programs and emergency relief in countries throughout the world. CSB is a highly nutritious, low-cost fortified food that is partially cooked and can be incorporated into different food preparations by the recipients.

The specifications for the CSB state that the mixture should contain 2 pounds of vitamin premix for every 200 pounds of product. These specifications are designed to produce a mean vitamin C content in the final product of 40mg per 100g. A sample of 8 readings from a production run has a mean of 22.50mg per 100g with a standard deviation of 7.19mg per gram.

Is there significant evidence that this production run does not meet the specifications? Use a 1% level of significance.

1. State the Null Hypothesis and the Alternative Hypothesis
2. Determine the test statistic.
3. Determine the P-value
4. Make a decision regarding the hypotheses based on the P-value and the Level of Significance.

Solution Summary

The solution details the step by step method for computing Z test statistic for comparing population mean with an excel spreadsheet of calculations to aid understanding.

2. Suppose you want to testthe claim that populationmean miu=3.5. Given a sample size of n=34 and a level of significance of alpha=0.01, when should you reject Ho?
3. Find the standardized test statistic t for a sample with n=15, sample mean=8.7, s=0.8, and alpha =0.05 if Ho is less than or equal to 8.4.
4. Find the sta

Using the data attached, perform the following:
Imagine that you have population data with an average height of 5 feet 10 inches. Conduct a one-sample t-test to determine whether your sample population is significantly different from the general population.
Imagine that you have population data with an average satisfaction

Tourism is one consideration for CoffeeTime's future, A survey of 1,233 visitors to mumbai last year revealed that 110 visited a small cafe during their visit. Laura claims that 10% of tourists will include a visit to a cafe.

A sample of n=9 scores is obtained from a normal population distribution with o-=12. The sample mean is M=60.
a- with a two-tailed test and o=.05,use the sample data to testthe hypothesis that thepopulationmean is u=65.
b- with a two-tailed test and o=.05, use the ample data to testthe hypothesis that thepopulation me

A sample size of 16 was randomly drawn from a normal population. Themean of these 16 cases was 47.6875 and the sample standard deviation was 19.0883. At an alpha level of .05, does themean of thepopulation differ significantly from 60?
