A researcher seeks to examine whether or not center-city families have significantly more children than suburban families. Random samples from both areas are gathered and the following sample statistics are computed.
|
Sample 1 (Center-City) |
Sample 2 (Suburban) |
|
Mean= 2.78 |
Mean = 2.37 |
|
Standard deviation= .95 |
Standard deviation= .63 |
|
N1= 101 |
N2= 125 |
Do families that reside in the center-city have statistically significantly more children than families that reside in the suburbs? Conduct a hypothesis test at 0.05 significance level (that is, α = 0.05). Summarize your conclusions in a few sentences.

21) A researcher wants to know whether there is a difference in the physical activity level of children during the morning and afternoon. He observes a total of 40 children (20 boys and 20 girls) from randomly selected schools during morning and afternoon recess and gives each child a score (out of 50) based on how much of the time they spend sitting, standing, walking or running. Each child receives a score in the morning and another in the afternoon....

Researchers wanted to determine if the psychological profile of healthy children was different than for children suffering from recurrent abdominal pain? (RAP) or recurring headaches. A total of 210 children and adolescents were studied and their psychological profiles were graded according to a child behavior checklist. Children were stratified in two age? groups: 4 to 11 years and 12 to 18 years. The results of the study are summarized in the accompanying table. Complete parts ?(a) through? (f) below. n...

A researcher wants to determine whether high school students who attend an SAT preparation course score significantly different on the SAT than students who do not attend the preparation course. For those who do not attend the course, the population mean is 1050 (? = 1050). The 16 students who attend the preparation course average 1200on the SAT, with a sample standard deviation of 100. On the basis of these data, can the researcher conclude that the preparation course has...
