For this assignment,
use data from W1 Assignment.
Compute a
t-test comparing males' and females' heights. You must
determine which type of t-test to compute.
Move your output into
a Microsoft Word document and write a one-paragraph, APA-formatted
interpretation of the results.

A statistics class collected data about male and female heights.
The sample of 143 females had a mean height of 64 inches with a
standard deviation of 2.84 inches. Assuming that the standard
deviation of all such female heights is 2.60 inches, use a 0.05
significance level to test the claim that women’s heights have a
mean different from 63.8 inches.
We are testing the claim about a (mean, proportion, standard
deviation): ______________________

You have collected data for 104 countries to address the
difficult questions of the determinants for differences in the
standard of living among the countries of the world. Your model has
the relative personal income (RelPersInc) determined by
the saving rate (SK) and population growth rate
(n). To test the predictions of this growth model, you run
the following regression:
= 0.339 – 12.894 × n + 1.397 × SK,
R2=0.621

On average, do males start smoking at an earlier grade than
females? Data from 94 12th grade boys that smoke and 108 12th grade
females that smoke found that the mean grade of first use of
cigarettes was 9.87 for boys (standard deviation of 1.75), and
10.17 for girls (standard deviation of 1.69).
a) Is this sufficient evidence at alpha =.05 that the mean grade
for first-time cigarette use is lower for boys than for girls? (10
points)
b) Calculate...

Given: Assume you have collected data from 150 subjects, and
that the distribution of the data is a "normal" distribution. The
mean of the scores is 37, with a standard deviation of 4.5. Using
the given information, calculate the 68% confidence interval. A
confidence interval represents a range of values, the lowest value
is references as the "lower bound", the highest value is referenced
as the "upper bound". Determine the lower and upper bounds for the
68% confidence interval. Round...

Let's say you have collected data from a large sample of
participants on some variable that you think is normally
distributed. In this case use IQ scores. Describe the variable and
state whether the scale of measurement is nominal, ordinal,
interval, or ratio, and why you came to that conclusion. What does
it mean to say the variable is normally distributed? What is
probability value and explain how a probability value of .05 in
your example is related to the...
