A random sample of 38 college students had left an average tip of $5.29, with a standard deviation of $1.03. A random sample of 47 non-college-student adults had left an average tip of $6.45, with a standard deviation of $0.86. Find the test statistic (2 decimals): Give the P-value (4 decimals):
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.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
Part 2 and 3
![A pizza delivery driver recently complained that the college
students he delivers to don't tip as much other adults. Test this
complaint at the a = 0.10 level of significance. Let µc represent the
average tip left by a college student and
tip left by other adults.(Round your results to three decimal
places)
represent the average
Which would be correct hypotheses for this test?
OH = Ort:1H Orl > Orl:0H
Η: με- μο, Η : μα > μο
Ho : µc = Ho, H1 : µc < µo
| Ho : µc = Po, Hị:µc + µo
A random sample of 38 college students had left an average tip of
$5.29, with a standard deviation of $1.03. A random sample of 47
non-college-student adults had left an average tip of $6.45, with a
standard deviation of $0.86.
Find the test statistic (2 decimals):
Give the P-value (4 decimals):
Which is the correct result:
O Do not Reject the Null Hypothesis
Reject the Null Hypothesis
Which would be the appropriate conclusion?
O There is significant evidence to suggest that college students
tip less, on average, than their non-college-student adult
counterparts.
OThere is not significant evidence to suggest that college
students tip less, on average, than their non-college-student
adult counterparts.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F24033adb-df78-46b5-9e2c-955a774154aa%2F0b99958d-3233-4e6d-8093-ed24d2c85ab9%2Fq2406lg_processed.jpeg&w=3840&q=75)
