For the following hypothesis, state the IV and DV with their respective measurement scales: "The gender of the interviewer affects the interviewee's anxiety levels (low/med/high)." Independent Variable = IV scale of measurement = Dependent Variable = DV scale of measurement =

How do you tell if a ANOVA is significant given the F value, p value, and eta squared? What does the post hoc test tell you?

I need help finding the test statistics and p-value. Please help

Iq and lead exposure. A sample of subjects with low lead levels in their blood was taken and another random sample was taken with high levels of lead in their blood. Use a 0.05 significant level to test claim that iq score of people p le w low lead levels is higher than the mean iq score of people w higher lead levels. Use p value approach      LLL N =78 SAMPLE MEAN=92.88 S=15.34 HLL N=21 SM= 86.90 S=8.99

Can you help me with the p-value I answered 0.034 which is incorrect

Suppose you will perform a test to determine whether there is sufficient evidence

Available below are amounts of arsenic in samples of brown rice from three different regions. The amounts are in micrograms of arsenic and all samples have the same serving size. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Do the amounts of arsenic appear to be different in the different​ regions? Given that the amounts of arsenic in the samples from region C have the highest​ mean, can we conclude that brown rice from region C poses the greatest health​ problem?     view the data table of the arsenic amounts.   Arsenic Amounts (micrograms)                             A 4.9 4.9 4.9 5.2 5.3 5.5 5.6 5.7 5.8 5.9 6.1 6.3   B 2.3 3.6 4.5 4.6 4.8 4.8 4.8 5.1 5.1 5.4 5.4 5.5   C 5.7 5.7 6.7 6.9 7.1 7.2 7.2 7.3 7.3 7.4 7.5 7.6               What are the hypotheses to​ test?   H0​: mu 1 equals mu 2 equals mu 3μ1=μ2=μ3   H1​: At least one…

A researcher collected BMI (Body Mass Index) of 50 students in an Engineering school. He found the mean BMI was much smaller than the median BMI. The reason for this might be Select the correct response: Several students had much larger BMI scores than the rest Several students had much smaller BMI scores than the other students All the students had smaller BMI scores, compared to national average The researcher made some measurement errors

A researcher believes that low BMI levels are indicators of eating disorders. He collects BMI of a sample of young adults identified as at risk for eating disorfers to see if their mean BMI is significantly below 18.5 What test would you use and why? (z test, independent t test, single sample t test, paired samples)

please help me fill the rest thanks
