Mr. Tabor believes that less than 75% of the students at his school completed their math homework last night. The math
teachers inspect the homework assignments from a random sample of 50 students at the school.
The math teachers inspect the homework assignments from a random sample of 50 students at the school. Only 68% of the
students completed their math homework. A significance test yields a P-value of 0.1265.
Interpret the P-value.
The probability that the null hypothesis is true is 0.1265.
The probability that the alternative hypothesis is true is 0.1265.
The probability of getting a sample proportion of 0.68 or more is 0.1265.
Assuming that the proportion of all students at Mr. Tabor's school who completed their homework last night is 0.75,
there is a 0.1265 probability of getting a sample proportion of 0.68 or less just by chance in a random sample of 50
students at the school.
O Assuming that the proportion of all students at Mr. Tabor's school who completed their homework last night is 0 75
there is a 0,1265 probability of getting a sample proportion of 0.68 or more just by chance in a random sample of so
students at the school.
