Did the lecture increase the number of days they meditate?

What is the t observed?

What is the appropriate decision?(You'll use this problem in the next question.)

How has attendance in a college class been affected by the change to distance education? Weekly absences of 2 separate, independent classes, one affected by distance ed and one not affected, were compared.

Here are the descriptive stats:

No Distance Ed Distance Ed

mean = 2

mean = 3
sd = .86 sd = .79

The t observed for this independent t test is 3.82.

Conduct all 5 steps of the hypothesis test, except for step 3 which has been given to you above.

Label each step:

1. state hypotheses (sentences and statistical notation)

2. set decision criteria (alpha, # tails, df, c.v.)

3. see above

4. make decision (reject or fail)

5. write up results (test and why, general result, evidence, direction of result)

*Note: 1 point for each item listed in parentheses.

How often do you go out dancing? This question was asked by a professional survey group on behalf of the National Arts Survey. A random sample of n1 = 97 single men showed that r1 = 24 went out dancing occasionally. Another random sample of n2 = 91 single women showed that r2 = 19 went out dancing occasionally. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some...
