The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level.
Step 2 of 2 :
Suppose a sample of 801 tenth graders is drawn. Of the students sampled, 577 read above the eighth grade level. Using the data, construct the 95%confidence interval for the population proportion of tenth graders reading at or below the eighth grade level. Round your answers to three decimal places.

The
state education commission wants to estimate the fraction of renth
grade students that have reading skills below the eighth grade
level. Step 2 of 2: Suppose a sample of 1649 tenth graders is
drawn. Of the students sampled, 1270 read above the eighth grade
level. Using the data construct the 95% interval for the population
proportion of tenth graders reading at or below the eighth level.
Round your answers to three decimal places.

A psychological test was standardized for a population of
tenth-grade students in such a way that the mean must be 500 and
the standard deviation must be 100. A sample of 90 twelfth-grade
students was selected independently and at random, and each given
the test. The sample mean turned out to be 506.7. On this basis,
can one say that the population distribution for twelfth grade
students would differ from that of tenth-graders?

A psychologist wants to study whether 6th grade or 10th grade
students have more empathy for others. Which method of research
would you prefer to have used: cross-sectional or longitudinal?
Explain your preference.
An education researcher is interested in students’ performance on a standardised reading test.
An education researcher is interested in students’ performance on a standardised reading test. The researcher believes that if students experience a particular form of positive coaching, then they will be more likely to perform better on the reading test.
This researcher is testing two hypotheses. The first is that the coaching boosts self-efficacy and has an effect on students’ reading test scores. The second is that this treatment effect is moderated by year in school. Past research has suggested that...
