Abbot Milk Company conduct a study about child growth and the relationship with milkconsumption daily. Children that stay in an urban area might have better growth becausetheir parent can afford to buy milk everyday compare to those stayed in rural area. To testthe claim, they measured the heights of 36 children from urban area and obtained a mean of92.8 cm. The population of children has heights with a mean of 91.4 cm and a standarddeviation of 3.6 cm (based on annual report). Use a 0.05 significance level to test the claimthat children from urban area have a mean height different from 91.4 cm.

Kayla Greene is a team lead for an environmental group for a certain region. She is investigating whether the population mean monthly number of kilowatt hours (kWh) used per residential customer in the region has changed from 2006 to 2017 She is concerned that changes such as more efficient lighting and the increased use of electronics and air conditioners are affecting the mean monthly number of kilowatt hours consumed per residential customer. Kayla investigates the data and assumes the population standard deviation for 2006 and 2017 using the data that were provided to her by local utility companies. Using data that was collected by her company, Kayla selects a random sample of residential customers who were active for all of 2006 and a separate sample of residential customers who were active for all of 2017. The population standard deviations and the results from the samples are provided in the accompanying table. Explain whether a hypothesis test for the difference between two…
It appears that people who are mildly obese are less active than leaner people. One study looked at the average number of minutes per day that people spend standing or walking. Among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately Normally distributed with 374 minutes and standard deviation 64 minutes. The mean number of minutes of daily activity for lean people is approximately Normally distributed with 522 minutes and standard deviation 104 minutes. A researcher records the minutes of activity for an SRS of 5 mildly obese people and an SRS of 5 lean people. (a) What is the probability that the mean number of minutes of daily activity of the 5 mildly obese people exceeds 400 minutes?
