Here are the 21 measurements (in mg/dL). 131, 139, 152, 161, 163, 165, 176, 181, 185, 185, 185, 189, 193, 194, 195, 206, 210, 213, 214, 233, 249 Send data to calculator Send data to Excel Frequency 10+ 6. 8. 6- 4 4 4. 2- 0--/- 200 225 250 150 Cholesterol level (in mg/dL) 125 175 2. 寸 2.

Below are the ages of the starters on two soccer teams.FC Looneys: 26, 31, 29, 30, 30, 26, 26, 31, 31, 31, 21Poppers FC: 25, 19, 22, 24, 26, 30, 25, 21, 23, 28, 26  describe theshape(skewed/symmetric, modality, outliers) for each.  Determine the appropriate measures of center and spread for each data set, according to the shapes.Then Calculate them.(Make sure to only select one measure of center and one measure of spread) Write a comparison, in context, between the two distributions. Make sure to use the appropriatemeasures of center and spread when comparing. Mention outliers, if any

Summarize the effect different kinds of outliers can have on a data set in terms of how we interpret whether we have a good model or not.

Are cigarettes bad for people? Cigarette smoking involves tar, carbon monoxide, and nicotine (measured in milligrams). The first two are definitely not good for a person's health, and the last ingredient can cause addiction. Use the data in the table above to make a stem-and-leaf display for milligrams of tar per cigarette smoked. (Enter NONE in any unused answer blanks.) Are there any outliers? A. Yes, 1.0 may be an outlier. B. No, there are no outliers.     C. Yes, 29.8 may be an outlier.

In a study, researchers wanted to measure the effect of alcohol on the hippocampal region, the portion of the brain responsible for long-term memory storage, in adolescents. The researchers randomly selected 23 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm. An analysis of the sample data revealed that the hippocampal volume is approximately normal with no outliers and x 8.18 cm and s=0.8 cm. Conduct the appropriate test at the a= 0.01 level of significance. State the null and alternative hypotheses. Ho: H H1: (Type integers or decimals. Do not round.) Identify the t-statistic. to = (Round to two decimal places as needed.) !! Identify the P-value. P-value = (Round to three decimal places as needed.) Make a conclusion regarding the hypothesis. the null hypothesis. There sufficient evidence to claim that the mean hippocampal volume is cm³ Statcrunch Next 8:01 SAMSUNG esc @ %23 $…
