HSCI 190 FINAL Study Set
Imagine you conduct a two-sided z test at the .05 significance level. You
complete all of your calculations and arrive at a p value of .003.
How would you interpret this data?
Reject the null hypothesis
Fail to reject the null hypothesis
Accept the null hypothesis
Accept the alternative hypothesis
Reject the null hypothesis
Something with a fixed number of trials, two dichotomous, and mutually
exclusive outcomes would be considered what type of probability
distribution?
Gaussian Distribution
, Page 2 of 20
Normal distribution
Binomial Distribution
Poisson Distribution
Binomial Distribution
In which of the following situations would you conduct a one-sample t test?
Examining one group with known population parameters
Comparing two independent groups
Examining one group with unknown population parameters
Comparing three or more independent groups
Examining one group with unknown population parameters
Levene's test can be used to check which statistical assumption?
Scale measurement
Independence
Normality
Equal variance
Equal variance
Achieving a healthy weight before pregnancy is recommended. In a
randomized control trial, researchers investigated the effectiveness of a
walking program compared to a dietary intervention. Researchers wish to
compare mean weight between the intervention groups. A Shapiro Wilk
normality test reveals a p value of 0.03. Which statistical test is most
appropriate?
Mann Whitney U
Unpaired t test
Wilcoxon Signed Rank
Paired t test
Mann Whitney U
Imagine you conduct a one-sample t test at a significance level of .05 and
identify the following results [t (7) = 2.365, p = .02]. How would you interpret
this output?
Reject the alternative hypothesis
Neither accept nor reject the null hypothesis
Accept the null hypothesis
Reject the null hypothesis

Reject the null hypothesis
What is the best description of the chi square distribution?
Bell-shaped
Uniform
Right skewed
Left skewed
Right skewed
A researcher is interested in comparing cancer biomarkers, such as cancer-
antigen 125 (CA125), between asymptomatic individuals who have a strong
family history of cancer, and age-matched, asymptomatic individuals who
have no close family history of cancer. Assuming the data are scale and
normally distributed, what statistical analysis would you use?
One sample z test
Independent two sample t test
Wilcoxon signed rank
Mann Whitney U
Dependent two sample t test
Dependent two sample t test
What does it mean when a 95% confidence interval for an independent t test
contains 0?
95% confident the groups are different
95% confident the groups are not different
95% confident the two means fall within the 2 standard deviations of 0
95% confident the true population equals 0
95% confident the groups are not different
dentify one key difference between the t distribution and the normal
distribution.
The t distribution is for sample sizes > 30
The t distribution is used for binomial events
The t distribution is defined by its degrees of freedom
The t distribution has a greater area than the normal distribution
The t distribution is defined by its degrees of freedom
Select the best definition of within group variability in an ANOVA.
The numerator of the F ratio
