A researcher report that exposure to honey causes ill effects to some people. What does this mean about the relationship between the p-value and the alpha in the study? If this conclusion is an error, what type would it be?
null hypothesis will be exposure to honey do not causes ill effects to some people
and alternate hypothesis : exposure to honey causes ill effects to some people
accordin to report exposure to honey causes ill effects to some people
so, p-value < alpha (reject null hypothesis)
if this conclusion is an error,then error would be TYPE I
[ type I error is null hypothesis is rejected when actually it is true ]

A researcher selects an alpha level of 0.15 for a study. What does this indicate about the statistical analysis of the study? the researcher is willing to accept a 15% chance that the null hypothesis will be rejected incorrectly the study results are likely to reveal a high level of clinical significance of the alternative hypthesis there is a high probability of making a type one error the researcher is willing to accept an 85% chance that the null hypothesis...
A researcher wishes to know if the data she has collected provide sufficient evidence to indicate a difference in mean serum uric acid level between normal individuals and individuals with Down' s syndrome. The data consist of serum uric acid readings on 12 individuals with Downâ€s syndrome and 15 normal individuals. The mean serum uric acid for individuals with Down's syndrome is 4.5 mg/100 ml and SD = 1 and the mean serum uric acid level for normal individuals is...

(select the best ONE) a. None of these b. Exposure is positively associated with the disease c. Exposure is definitely causative of the disease d. Exposure is not associated with the disease e.
