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.

Assume both follow a Normal distribution. What can be concluded at the the a = 0.05 level of significance
level of significance?
For this study, we should use Select an answer
a. The null and alternative hypotheses would be:
Ho: Select an answerv Select an answerv Select an answerv (please enter a decimal)
H: Select an answerv Select an answerv Select an answerv (Please enter a decimal)
b. The test statistic ?v =
(please show your answer to 3 decimal places.)
C. The p-value =
(Please show your answer to 4 decimal places.)
d. The p-value is ?v a
e. Based on this, we should Select an answerv the null hypothesis.
f. Thus, the final conclusion is that ...
O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude
that the population mean time in the shower for the poor is not the same as the population
mean time in the shower for the rich.
O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude
that the mean time in the shower for the ten poor people that were surveyed is not the same
as the mean time in the shower for the eleven rich people that were surveyed.
O The results are statistically insignificant at a = 0.05, so there is insufficient evidence to
conclude that the population mean time in the shower for the poor is not the same as the
population mean time in the shower for the rich.
O The results are statistically insignificant at a = 0.05, so there is statistically significant
evidence to conclude that the population mean time in the shower for the poor is equal to the
population mean time in the shower for the rich.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4f1af382-e5ff-418b-a9e7-b713cc30d9f8%2F7c16dbd0-785a-4e53-bf1e-9653627b09a6%2Ffx4vf8i_processed.jpeg&w=3840&q=75)
