Consider: Sodium content in a particular brand of tortilla chips. it) A random sample was selected in order to estimate the true sodium content. Sample results: Sample size: 30 Sample Mean: 92 g Sample standard deviation: 4 g. a. The sample result of f = 92 9 can be used as a point estimate for the mean amount of sodium per serving. At the 90% Condence Level, what is the Margin of Error associated with this estimate? b. Provide the 90% Confidence Interval for the Mean amount of sodium per serving. c. There is a claim that, on average. this brand of tortilla chips has the sodium content of 90 gr. Specify the null and alternative hypotheses that you would use to test this claim. H0: Ha: Is this hypothesis testing a one-tail or two-tail test? d. Provide the t-test statistics for the hypothesis testing in part c. e. Find the critical value in t-student distribution with 29 degree of freedom that associate with the signicant level of 5%
