Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency o…
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

Question
In a random sample of
7
cell​ phones, the mean full retail price was
​$539.80
and the standard deviation was
​$193.00.
Further research suggests that the population mean is
​$425.21.
Does the​ t-value for the original sample fall between
−t0.99
and
t0.99​?
Assume that the population of full retail prices for cell phones is normally distributed.
The​ t-value of
t=nothing
▼
 
does
does not
fall between
−t0.99
and
t0.99
because
t0.99=nothing.
​(Round to two decimal places as​ needed.)
