Question
Chapter 7, Problem 3TP
1.
To determine
To create: A null hypothesis, directional hypothesis and nondirectional hypothesis that explains the effects of attention span on out-of-seat classroom behavior.
1.
Expert Solution
Explanation of Solution
Answers will vary. One of the possible answers is given below:
Explanation:
Null hypothesis: The effect of attention span is measured by the attention span observation, spans consists same frequency of out of seat behavior as those with long attention span.
Directional: The effect of attention span is measured by the attention span observation, spans consists high frequency of out of seat behavior as those with long attention span.
Non directional: The effect of attention span in measured by the attention span observation, spans consists differ in frequency of out of seat behavior as those with long attention span.
2.
To determine
To create: A null hypothesis, directional hypothesis and nondirectional hypothesis that explains the relationship between the quality of a marriage and the quality of the spouses’ relationships with their siblings.
2.
Expert Solution
Explanation of Solution
Answers will vary. One of the possible answers is given below:
Explanation:
- Null hypothesis: There is no relationship between the quality of a marriage and the quality of the spouses’ relationship with their siblings.
- Directional Research hypothesis: There is smallest relationship between the quality of a marriage and the quality of the spouses’ relationships with their siblings.
- Non directional research hypothesis: There is a relationship between the quality of a marriage and the quality of the spouses’ relationship with their siblings.

Suppose an experiment was conducted to compare the mileage(km) per litre
obtained by competing brands of petrol I,II,III. Three new Mazda, three new
Toyota and three new Nissan cars were available for experimentation. During the
experiment the cars would operate under same conditions in order to eliminate
the effect of external variables on the distance travelled per litre on the assigned
brand of petrol. The data is given as below:
Brands of Petrol Mazda Toyota Nissan
I 10.6 12.0 11.0
II 9.0 15.0 12.0
III 12.0 17.4 13.0
(a) Test at the 5% level of significance whether there are signi
cant differences among the brands of fuels and also among the cars. [10]
(b) Compute the standard error for comparing any two fuel brands means. Hence
compare, at the 5% level of significance, each of fuel brands II, and III with
the standard fuel brand I. [10]
