Fill in the blank for the following given the scenario that we have measured the pulse rate value of a sample with the variables of gender, ethnic group (4 groups), marital status (5 categories), age and weigh. What statistical test of significance should be used for finding if: pulse rate average is different when measured across each of 4 months for the same sample___ pulse rate can be predic fed by age___ pulse rate average is higher for males than females___ pulse rate average a year later is different from the original average for the same people___ marital status is related to gender___ pulse rate value is predicted by age and height___ pulse rate average is different across ethnic group___ pulse rate is related to height ___ there is an interaction between gender and ethnic group using pulse rate as the dependent measure___ pulse rate average for the sample is higher than 72___

Solution

As there are multiple parts to the question, the first 4 will be answered:

1. For observing if the average is different across each of the 4 month for the same sample, we check the signficance of the coefficient of time variable, after defining a time series with unit of 1 month.

We can also use ANOVA with 1treatment and 4 levels (one for each month)

2. For this, we perform a simple linear regression and conduct a t-test on slope coefficient.

Answer:Regression of pulse rate on Age and t-test of slope coefficient = 0

3. For this, we use 2 sample independent t-test, to see if the average of males is equal to that of females.

4. For this,we check the signficance of the coefficient of time variable, after defining a time series with unit of 1 year.

We can also perform a t-test to check if the mean of the data is equal to the original avergae.
