- Doritos chips are one of the most popular chips in the year 2020. Frito-Lay produces snack-sized bags of Doritos with 1.75-ounce bags. Unfortunately, Frito-Lay has received many complaints that the bags of chips lack the promised amount of chips. PepsiCo, the owner of Frito-Lay, decide to run an internal investigation of their Doritos chip production. They sample around 500 bags of chips to discover that they found an average of 1.59 ounces with a standard deviation of .12 ounces. Conduct a hypothesis test with an alpha-level of .05. Should they change their production of Doritos chips to match the 1.75 ounces on the bag?Give a general description of the nature of and relationship between Type I and Type II errors.The ANOVA procedure is a statistical approach for determining whether or not... the means of more than two populations are not equal the means of more than two samples are not equal the means of more than two populations are equal the means of more than two samples are equal None of the above are true
- You are interested in studying the frequency of falls leading to hospitalization among an elderly population attending your outpatient clinic. You identify 862 eligible patients over a 4 year period, of whom 223 were followed for 4 years, 354 for 3 years, 112 for 2 years, and 173 for 1 year. During the 4 year period, there were 98 falls requiring hospitalization. What is the incidence density rate of falls leading to hospitalization per 1,000 person-years in this population? (Please give your answer rounded to the nearest integer).Define degrees of freedom in the context of ANOVAWhat is difference between type 1 and type 2 errors?
