Question 3: A travel agent wants to know if the proportions of satisfied customers at two different resorts are different. In a random sample of 200 customers at Resort A, 160 were satisfied. In a random sample of 250 customer at Resort B, 172 were satisfied. At the 1% level of significance, do the resorts differ in customer satisfaction? (a) State the hypotheses for this test and define one of the parameters of interest in full context. (b) Verify that the assumptions for the test are met. 1. Independent Groups Assumption: 2. Independence Assumption, checked by the Randomization Condition: 3. Sample Size Assumption, checked by the Success/Failure Condition: (c) Under the null hypothesis, compute the ingredients needed to calculate the test statistic. Pi - P2 = E(Pi - P2) = Ppool SEpool (P1 – P2) = (d) Compute the test statistic for this test. (e) Draw a rough normal diagram for this test statistic and compute the p-value for the test.
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
