I don't know what to do..please help.The doctor estimates that more than 220 out of the 500 patients in his database take vitamin each year. A random sample of 60 patients shows that 27 o them take vitamin each day.
how to use a proportion to predict the total number of patients who take vitamin each day?
27/60 = x/500
x = 225
To use a proportion to predict the total number of patients who take vitamin each day, you can follow these steps:
Step 1: Calculate the proportion of patients from the random sample who take vitamin each day. In this case, the proportion is given by dividing the number of patients who take vitamin by the total number of patients in the sample.
Proportion = Number of patients who take vitamin each day / Total number of patients in the sample
In this example, the proportion is 27/60 = 0.45.
Step 2: Use the proportion to estimate the total number of patients who take vitamin each day in the entire patient population. To do this, multiply the proportion by the total number of patients in the population.
Estimated total number of patients who take vitamin each day = Proportion x Total number of patients in the population
In this case, we are given that there are 500 patients in total. Let's calculate the estimate:
Estimated total number of patients who take vitamin each day = 0.45 x 500 = 225
Therefore, you can predict that approximately 225 patients in the entire patient population take vitamin each day.
