The average amount of time it takes for couples to further communicate with each other after their first date has ended is 3.06 days. Is this average different for blind dates? A researcher interviewed 53 couples who had recently been on blind dates and found that they averaged 3.5 days to communicate with each other after the date was over. Their standard deviation was 1.096 days. What 0.10 level of significance? can be concluded at the the a = a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Но: H1: c. The test statistic t (please = show your answer to 3 decimal places.) d. The p-value (Please show your answer %3D to 4 decimal places.) e. The p-value is (s v a f. Based on this, we should [ reject the
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 two parameters.
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 or measure of central tendency is a central or typical value for a probability distribution.
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 comparison between two scores that belong to different normal distributions.
