What is a one sample t interval for a mean
The test name for conducting a Significance Test for a Mean
What is a one sample t test for a mean
What is the test name for conducting a Matched Pair Procedures
What is a one sample t procedures
What is the test name for conducting a Confidence Intervals for a Difference in Means
What is a Two Sample T Interval for a Difference between Two Means
What is the test name for conducting a Significance Test for a Difference in Means
What is a Two Sample T test for a Difference in Means
The calculator function to calculate t*
What is invT
The null and alternative hypothesis for a Significance Test for Means if we're trying to find a difference between from the null
What is
Ho: M=Mo
Ha: M is not equal to Mo
What does we write in our Communicate Section
What is
Ho:ud=0
Ha:ud___o
ud=in words a=
What 2-SampTInt in the test section of the calculator
The calculator function to conduct a Two Sample T Test for a Difference in Means
What is 2-SampTTest in the test section in the calculator
t* has a 90% Confidence Interval with n=5
We have a p-value of 0.023 and our significance level is 0.05
What is since our p-value of 0.023 is lower than a=0.05, we can reject the null hypothesis
ME=1
95% Confidence Level=1.96
SD=5
What is n=96.04=97
The sentence starter for Confidence Intervals for a Difference in Means in our conclusion
What is We are ____% confident that the true mean difference in (context) is between (the interval)
We have a p-value of 0.064 and our significance level is 0.05
What is since our p-value of 0.064 is greater than a=0.05, we fail to reject our null hypothesis.
The closer the t-distribution will move towards the standard normal distribution
Our sample size is less than 30 in the Normal Condition
What is we have to have either the original population to be approx normally distributed or graph the sample data to check for outliers or strong skewness
This is a special case of a randomized block design
What is a Matched Pair designs
In this condition, there are two random samples taken or randomly assigned to two groups
What is the Random Condition
Both populations are under the sample size of 30
What is both populations have to be normally distributed or one or both graphs have to have no outliers or strong skewness
We don't know the population standard deviation so we use the standard deviation from our sample
What is a t-statistic
What is Independent
The margin of error to determine a sample size for a confidence interval for a mean
What is ME=z* (standard deviation/square root of n)
This is the smaller of n1-1 and n2-2
What is the Degrees of Freedom
The null and alternative hypothesis for a Two Sample T Test for a Difference in Means and to see if the first mean is lower than our second mean
What is
Ho:u1=u2
Ha:u1<u2
