Name the Variable
What letter/symbol represents sample size
N/n
how do you start a hypothesis test
Ho: Mew =, <=, >=
Ha: Mew >, <, not equal to
Mew - 8.5
Xbar - 9.6
CV - 0.05
n - 40
Z - test
What letter/Symbol represents Sample size
X- bar
write the formula for Degrees of freedom
DF = n - 1
the average salary for teachers in a school year is given below
43,000 - 42500 - 44,000 - 39400
41020 - 43200 - 39900
T - test
What symbol represents for proportions in a hypothesis test
P = population and p^ is the sample
Write the formula for a z - test
z = (x-bar minus mew) divided by Population S.D. divided by square root of n
I have a sample size of 34
Z - test
What symbol represents Population Stand Deviation and sample S.D.
Sigma ( Side ways 6) for population and little "s" for sample
Write the formula when you are solving a t - test
t = (x-bar minus mew) divided by Population S.D. divided by square root of n
I have a sample size of 30
t - test
What symbol represents population mean
Mew (the Weird M symbol)
Write the formula when solving for a proportion
p = P-hat - p divided by Square root of p times q divided by N.
I have a sample size of 32 but don't my standard deviation
t -test bc population SD is unknown
