Question

The
National Center for Education Statistics would like to test the
hypothesis that the proportion of Bachelor's degrees that were
earned by women equals o.60. A random sample of 140 college
graduates with Bachelor degrees found that 75 were women. The
National Center for Education Statistics would like to set
significance level of o.10. What is your conclusion?

Answer #1

A report from the national center for education
statistics claimed that more than 2/3 of undergraduates get some
form of financial aid you take a random sample of 400 under
graduates from the US and found that 300 to receive some form of
financial aid test the claim at a equals 0.05. use this scenario
to
1)state the alternative and null hypothisis
2) Calculate the test static
3) Identify the value
4)make your decision
5) interpret the results

The Department of Education would like to test the hypothesis
that the average debt load of graduating students with a bachelor's
degree is equal to $17,000. A random sample of 34 students had an
average debt load of $18,200. It is believed that the population
standard deviation for student debt load is $4,200. The α is set to
0.05. (a) Perform a hypothesis test showing all steps.

The National Center for Education Statistics reports that the
proportion of college freshmen who return to the same school for
their sophomore year is 0.69. Suppose we select a random sample of
480 freshmen from across the nation.
Question 1. What is the expected value of the sampling
distribution model for the proportion of 480 freshmen that will
return to the same school for their sophomore year?
Question 2. What is the standard deviation of the sampling
distribution model for...

The Department of Education would like to test the hypothesis
that the average debt load of graduating students with a Bachelor's
degree is equal to $17,000. A random sample of 34 students had an
average debt load of $18,200. It is believed that the population
standard deviation for student debt load is $4,200. The Department
of Education would like to set α = 0.05. The
conclusion for this hypothesis test would be that because the
absolute value of the test statistic...

The Department of Labor would like to test the hypothesis that
the average hourly wage for recent college graduates is less than
$20. A random sample of 24 recent college graduates averaged $19.30
per hour with a standard deviation of $3.20 per hour. The
Department of Labor would like to set ? = 0.10. Use the critical
value approach to test this hypothesis. please either type this
answer or be very careful to make your handwriting legible

The Centers for Disease Control (CDC) would like to test the
hypothesis that the proportion of obese adults in the U.S. has
increased this year when compared to last year. A random sample of
120 adults this year found that 9 were obese. Last year, a random
sample of 150 adults found that 15 were obese.
If Population 1 is defined as this year and Population 2 is
defined as last year.
a) Define the null hypothesis and alternative hypothesis....

A local school board would like to test the hypothesis that the
proportion of Americans who think unions have a positive effect on
schools has decreased this year when compared to last year. A
random sample of 160 Americans last year found that 48 felt unions
have a positive effect on schools. A random sample of 140 Americans
this year found that 28 felt unions have a positive effect on
schools. Define Population 1 as this year and Population 2...

The Department of Education would like to test the hypothesis
that the average debt load of graduating students with a bachelor’s
degree is equal to $17,000. A random sample of 34 students had an
average debt load of $18,200. It is believed that the population
standard deviation for student debt load is $4,200. The α is set to
0.05. The confidence interval for this hypothesis test would be

Based on the National Center of Health Statistics, the
proportion of babies born at low birth weight (below 2,500 grams)
in the United States is roughly .078, or 7.8% (based on all the
births in the United States in the year 2002). A study was done in
order to check whether pregnant women exposed regularly to second
hand smoke increases the risk of low birth weight. In other words,
the researchers wanted to check whether the proportion of babies
born...

Recently, the National Center for Education Statistics reported
a study of a random sample of 1990 public school teachers whose
first year teaching was in 2007-2008. The study found that 5 years
later (in 2013) 17% of the teachers had left the profession.
However, amongst the 1580 teachers who were assigned a mentor in
their first year of teaching 14% had left the profession compared
with 29% of the 410 teachers...
