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.

Question

A realtor claims that in a certain neighborhood, the average house is
worth $200,000. Having been house shopping in that neighborhood, you
do not believe the claim and wish to provide evidence that the claim is not
true. You collect a random sample of 200 recent house sales in that
neighborhood, finding an average sale price of $203,910 with a standard
deviation of $21,597.
Correctly using a hypothesis test, which of the following statements is
most accurate?
You cannot reject the null at the 10% level of significance
O You can reject the null at the 10% level of significance, but cannot reject the
null at the 5%, 2%, or 1% level of significance
You can reject the null at the 10% and 5% level of significance, but cannot
reject the null at the 2%, or 1% level of significance
You can reject the null at the 10%, 5%, and 2% level of significance, but cannot
reject the null at the 1% level of significance
You can reject the null at the 10%, 5%, 2%, and 1% level of significance

A survey of 25 customers sampled at one of the restaurants found the average lunch bill per customer to be ?¯=$14.50 . Based on previous surveys, the restaurant informs the marketing manager that the standard deviation is ?=$3.50 . To address the CEO’s conjecture, the marketing manager carried out a hypothesis test of ?0:?=13.50 vs. ??:?>13.50 and obtained a ?‑value = 0.77. The marketing chooses a significance level of ?=0.10. If he uses this significance level throughout his work, how often will he reject a true null hypothesis? Group of answer choices a.He will reject 10% of all true null hypotheses. b.
