It has been estimated that 20% of the students at a large college own bicycles. In order to determine for accuracy of this estimate a random sample of students from the college is selected. Each student in the sample is asked whether he or she owns a bicycle. Using the data obtained from the sample, a test is conducted of the null hypothesis
It has been estimated that 20% of the students at a large college own bicycles. In order to determine for accuracy of this estimate a random sample of students from the college is selected. Each student in the sample is asked whether he or she owns a bicycle. Using the data obtained from the sample, a test is conducted of the null hypothesis Ho: p = 0.2 again st the alternative hypothesis Ha: p does not equal 0.2, where p is the proportion of all students at the college who own bicycles. Of the following, which is the best interpretation of p-value for the test?
A) The
B) The probability that Ho is true.
C) The probability that Ha is true
D) The probability of getting a sample proportion at least as far from 0.2 as the one obtained, given that Ha is true
E) The probability of getting a sample proportion at least as from 0.2 as the one obtained, given that Ho is true.
Given that
The Null and alternative hypothesis is.
H0 : p=0.2
Ha : p≠0.2
