Question
Transcribed Image Text:The data shown below represents the age (in weeks) at which babies first crawl, based on a survey of 12 mothers.
Data: 52, 30, 44, 35, 47, 37, 56, 26, 37, 36, 52, 37
(a) Draw a normal probability plot to determine if it is reasonable to conclude the data come from a population that is normally distributed. Choose the correct answer below.
Options:
- A. A plot showing a linear pattern where expected z-scores and age (in weeks) increase together.
- B. A plot showing a minor deviation from linearity.
- C. A plot showing a strong linear pattern suggesting normality.
- D. A plot with noticeable deviation from linearity.
Since the correlation between the expected z-scores and the observed data is \( \_\_\_\_ \), \( \_\_\_\_\_\_\_\_\_\_ \) the critical value, it \( \_\_\_\_\_\_\_\_\_\_ \) reasonable to conclude that the data come from a population that is normally distributed.
*(Round to three decimal places as needed.)*
(b) Draw a boxplot to check for outliers. Choose the correct answer below.
Options:
- A. A boxplot displaying no apparent outliers.
- B. A boxplot with an indication of potential outliers.
- C. A symmetric boxplot with extremes within normal range.
- D. A boxplot with skewness showing possible outliers.
Does the boxplot suggest that there are outliers?
If no: There are no points that are greater than the third quartile or less than the first quartile.
