Variable | Obs Mean Std. Err. Std. Dev. [95% Conf. Interval]

---------+--------------------------------------------------------------------

alctry | 16,149 991.0647 .0066429 .8441679 991.0517 991.0777

------------------------------------------------------------------------------

mean = mean(alctry) t = 1.1e+05

Ho: mean = 292.0672 degrees of freedom = 16148

Ha: mean < 292.0672 Ha: mean != 292.0672 Ha: mean > 292.0672

Pr(T < t) = 1.0000 Pr(|T| > |t|) = 0.0000 Pr(T > t) = 0.0000

- Write out the research question and write a short paragraph 3-4 sentences presenting the findings.

Null hypothesis (H0): The true difference in mean
hemoglobin change for pregnant women not exposed to herbicides
versus those who are somewhat exposed is 0 g/dL.

hemoglobin change for pregnant women not exposed to herbicides
versus those who are somewhat exposed is not 0 g/dL.

H0: Mean = 7.5
HA: Mean not equal to 7.5
X Bar = 8.5, SD = 1.2. n = 670, confidence interval: 95%
2)
H0: Mean = 125
HA: Mean no equal to 125
X Bar = 135, SD = 15, n = 500, confidence interval: 95%

t-Test for One Sample
Mean
1. Let’s assume that lab rates require an average of 32 trials
in a complex water maze before reaching a criterion of three
consecutive error-less trials. To determine whether a mildly
adverse stimulus has any effect on performance, a sample of 7 lab
rats were given a mild electric shock just before each trial.
Given research results that show a sample mean of 34.89 and a
sample standard deviation of 3.02, test the null hypothesis...

you are calculating a confidence interval for the population
mean. Find the critical value t* from the t-Distribution Critical
Values table for each of the following situations
A 95% confidence interval based on n = 12 observations.
A 99% confidence interval from a sample of two observations.
A 90% confidence interval from a sample of size 1001.
2. Suppose you conduct a hypothesis test for the following
hypotheses from a sample of n = 25 observations, and you calculate
a...

The California Standardized Testing and Reporting (STAR) dataset
contains data on test performance, school characteristics and
student demographic backgrounds. The data used here are from all
420 K-6 and K-8 districts in California with data available for
1998 and 1999. Test scores are the average of the reading and math
scores on the Stanford 9 standardized test administered to 5th
grade students. TESTSCR: AVG TEST SCORE (= (READ_SCR+MATH_SCR)/2 );
STR: STUDENT TEACHER RATIO (ENRL_TOT/TEACHERS); Using the provided
table, write down...
