roctor es ces formula and a similar problem. During the 2017-2018 flu season, a random sample of 100 hospitalizations related to flu was studied. It was later determined that 10 patients have died. A similar study during the 2018-2019 flu season revealed that in a random sample of 80 hospitalized cases related to flu, there were 9 deaths observed. At 10% significance level, test the claim that the percentage of deaths in 2017-2018 is different from the percentage of deaths in the 2018-2019 season. Procedure: Two proportions Z Hypothesis Test く Assumptions: (select everything that applies) Population standard deviations are known Population standard deviation are unknown The number of positive and negative responses are both 5 or more for each sample Sample sizes are both greater than 30 Independent samples Simple random samples Normal populations Population standard deviation are unknown but assumed equal Paired samples Step 1. Hypotheses Set-Up: HPP Hap-P 0 0 =0 where p and p: are…
Hypothesis TestingA machine produces nails with a mean length of 5 cm.A sample of 25 nails has a mean of 4.9 cm and standard deviation 0.2 cm.Test at 5% significance level whether the machine is producing nails of correct length.
The marks of 10 students are: 40, 45, 45, 50, 50, 50, 55, 55, 60, 65.Find the mode.
