You wish to test the following claim (HaHa) at a significance level of α=.02. Ho:p=0.59 Ha:p>0.59 You obtain a sample of size n=137 in which there are 99 successful observations. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution. a.) The sample proportion p^= (write as a fraction) b.) What is the test statistic for this sample? (Report answer accurate to 2 decimal places.) test statistic = c.) What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = d.) The p-value is... a.)less than (or equal to) αα b.)greater than α
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
You wish to test the following claim (HaHa) at a significance level of α=.02.
Ho:p=0.59
Ha:p>0.59
You obtain a sample of size n=137 in which there are 99 successful observations. For this test, you should NOT use the continuity correction, and you should use the
a.) The sample proportion p^= (write as a fraction)
b.) What is the test statistic for this sample? (Report answer accurate to 2 decimal places.)
test statistic =
c.) What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =
d.) The p-value is...
- a.)less than (or equal to) αα
- b.)greater than α
