Anew city mayor would like to determine if community members are paying less for gas prices in his city this year compared to last year. he surveys 16 random community members and conducts hypothesis test about the mean cost of gas prices, which was 2.45 dollars last year, using a 5% significance level. determine the critical value(s) using the partial t-table above. if entering two critical values, use ±

Step-by-step explanation:

Let be the population mean and   be the actual mean price.

By considering the given information, we have

Given : Sample size : n= 16, which is a small sample so the test applied here is t-test.

Significance level :

Degree of freedom =

By using the standard normal distribution t-table, the critical value for t-test will be :-

Hence, the  the critical value will be

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
