Question 3 Based on the nutrition facts of a famous brand of potato chips. its average sodium content is 85 mg per serving (1 bag) with a standard deviation of 2.2 mg. Sixty - four (64) bags were taken as sample. Assume that the variable is normally distributed. Prompts Submitted Answers What is the mean of the sampling distribution? 85 Find the standard error of the sampling 0-275 distribution of the sample mean. Using the central limit theorem. 0.0018 nd the probability that the average sodium content will be larger than 85.8 mg? Find the range of values where 83-15 the middle 80% of the distribution of sample means will lie (A to B). The value of A Is Following the range of values 85.35 problem (middle 80%). the value of Bis Question 5 The Incubation period refers to the number of days between being In contact with an Infected person and actually showing symptoms of being infected. Health care professionals say that the mean incubation period of COVlD19 Is 12 days with a standard deviation of 2 days. This accounts for the 14-day quarantine period. With the recent upsurge of Infections due to the different variants of the virus. a group of researchers surveyed 100 conrmed cases and found that the mean Incubation period is 11.5 days. Is there enough evidence to show that the mean Incubation period has actually changed? Which of these signicance levels will lead to a rejection of the Ho? a>06% a5% a 12 0 Ho: u=12. Ha: p
