A psychologist is investigating whether or not elderly people (age 60 to 70) have a different speaking speed in everyday conversation as compared to middle age people (age 20 to 40). The psychologist test 20-40 years old and 60-70 years old participants and determines speaking speed for each participant. Formulate in words the null and research hypotheses in the context of this study. The formulations should involve the dependent and independent variables used in the study. However, do not use the phrases “dependent variable” or “independent variable” as such. Do not use any mathematical symbols or expressions.

Here it is given that , a psychologist is investigating whether or not elderly people (age 60 to 70) have a different speaking speed in everyday conversation as compared to middle age people (age 20 to 40).
The null and alternative hypotheses are as follows;
Null Hypotheses :
Elder people have a same speaking speed as compared to middle age people.
Note that , older adults produce less fluent and less complex speech in comparison with younger adults.
Alternative Hypotheses :
Elder people have a different speaking speed as compared to middle age people.
