Using the descriptive statistics for the weight of the babies in ounces suppose a friend of yours has given birth to a 10 pound 3 ounce baby. Is this unusual? why or why not?
What are the descriptive statistics for newborn weights? Just from my personal experience with newborns, that is an unusually heavy baby.
Z = (score-mean)/SD
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score. Use that data to indicate how usual the weight is.
To determine whether a 10-pound 3-ounce baby is unusual in terms of weight, we need to refer to the descriptive statistics of the weight of babies in ounces. Unfortunately, you have not provided the necessary descriptive statistics. However, I can explain the steps you can take to determine whether the weight is unusual or not, assuming you have the relevant information.
1. Obtain the descriptive statistics: This includes calculating the mean, standard deviation, minimum, maximum, and other relevant statistics for the weight of babies in ounces.
2. Convert 10 pounds 3 ounces to ounces: Since the descriptive statistics are likely in ounces, we need to convert the weight of the baby from pounds and ounces to ounces. One pound is equal to 16 ounces, so 10 pounds would be 160 ounces. Add 3 more ounces to get a total of 163 ounces.
3. Compare the baby's weight to the descriptive statistics: Once you have the descriptive statistics (mean, standard deviation, etc.), you can compare the baby's weight (163 ounces) to these values.
- If the baby's weight is close to the mean and falls within one standard deviation, it can be considered a common or normal weight.
- If the baby's weight is significantly higher or lower than the mean and falls outside of the range of one or two standard deviations, it can be classified as unusual or unusual.
- If the baby's weight is very far from the mean and falls outside the range of two or more standard deviations, it can be considered extremely unusual or an outlier.
Without the specific descriptive statistics, it is not possible to definitively determine if a 10-pound 3-ounce baby is unusual. However, by following the steps outlined above, and using the descriptive statistics, you can make an informed conclusion about whether the baby's weight falls within a normal range.
