Answer #1

Hypothesis, in other words, is the claim made in a statement. It may or may not be true. For example: a report is certain that mean life of a television set is atleast 1 year. This claim is an example of null hypothesis. For example: a report is certain that mean life of a television set is not 1 year. This is an example of alternative hypothesis.

Type 1 error: When a false hypothesis is considered true

Type 2 error: When a true hypothesis is considered false

An experiment is done to compare the effects of three situations: Situation 1 is tested in a “no-stress,” baseline situation; Situation 2 does a mental arithmetic task; and Situation 3 participants do a mock job interview. At the end of each session, the participants self-report their anxiety on a scale that ranges from 0=no anxiety to 20=extremely high anxiety. The researcher wants to know whether, overall, anxiety levels differed across these three different situations. Each of the 21 participants was...

Research is an integral part of all professional fields. Designing a research study can be a complicated task that can be simplified if the appropriate techniques can be identified. This assignment will give you the opportunity to design an experiment, including finding relevant prior research, determining the appropriate sample, data analysis techniques, and discuss the results you hope to see. Working from the topic chosen earlier in the topic selection, you will be designing your own statistical study. In a...

A psychologist has developed a drug to reduce schizophrenia symptoms.  15 participants with schizophrenia are recruited.  The number of schizophrenic symptoms is recorded before the drug is administered (baseline), and again 3 months after the drug was first administered (follow-up). The data indicate that after receiving the drug, participants schizophrenic symptoms decreased by an average of MD =10.6, with a SS = 325. Conduct the appropriate hypothesis test to determine if the treatment had any effect (non-directional) at alpha=.05.  Specify the following: 1....

2. In a study examining the effect of caffeine on reaction time, Liguori and Robinson (2001) measured reaction time 30 minutes after participants consumed one 6-ounce cup of coffee and they used standardized driving simulation task for which the regular population averages μ = 415 msec. The distribution of reaction times is approximately normal with σ = 40. Assume that the researcher obtained a sample mean of M = 400 msec for the n = 36 participants in the study....

Interpret the negative consequence of a Type 1 error in the following example: Imagine a doctor is prescribing a very expensive medication with potentially dangerous side effect with over dosage. A previous study demonstrated the 5 pills is probably the lowest dosage to eradicate the illness in most adults. So the hypothesis test would be: Null hypothesis: dosage for null recovery in adults is greater than or equal to 5 pills. Alternative hypothesis: dosage for full recovery in adults is...
