The meanPEF for children free of asthma is 306. An investigator wants to test whether children with asthma have restricted PEF. A sample of 40 children are studied and their mean PEF is 279 with a standard deviationof 71. Is there statistical evidence of a lower mean in PEF in children with asthma? Alpha = 0.05
Critical z value =
Ho: children with asthma do not have a lower mean in PEF
Ha: children with …
The solution gived detailed steps on hypothesis tesing when alpha is 0.05. All formula and calcuations are shown and explained.
