As a psychiatrist you developed a test to measure happiness. Test the claim that the mean measure of happiness for females is equal to themean measure of happiness for males. Use a significance level of .10. The data is given below. (although you could label group 1 to bemale or female and get the same answer at the end, the middle would vary a little. So to match with me call group 1 females) (3 decimals)females males9.67.68.96.96.79.66.35.87.19.46.17.3C: μ1=μ2HA;μ1#μ2Ho: [Select][Select]8.47.99.7P=[Select]8.8[Select]7.8Pis [Select]The data [Select]Critical value/s is [Select]+=-1.849+(although you are rounding to 3 decimals this one ends up with only 2)the claim.+

You have data set withn = You add one value to the data set, x10 9 values and a mean of = 31. 42. ¿What is the mean of the expanded data set?
You are a data scientist investigating a new dataset you just received. After some preliminary analysis, you discover that the dataset has a median of 81.45, a Q3 of 86.71, and an IQR of 10.05. Use this information to create a boxplot diagram. What is the value of the lower fence? Note: 1- Only round your final answer. Round your final answer to two decimal places.
Why is the answer not a Median but its neither Median or Altitude?
Researchers wondered whether the size of a person's brain was related to the individual's mental capacity. They selected a sample of 5 females and 5 males and measured their MRI image pixel counts and IQ scores. Females Males MRI IQ MRI IG The data is reported to the right.
