Answer:
0.7
Step-by-step explanation:
An outlier of the data set is the data point which is quiet different from the rest of the data points or we can say that they lie outside the the other points.
Since in the given data, the similar data points ranges from 3.1 to 5.8, all points are nearly in between in this range but 0.7 is the only point which does not lie in this range. Hence, 0.7 is the outlier of the given data set.
One can also find the outlier by arranging the given data set from lowest to greatest that is if we arrange 3.1, 5.3, 4.3, 0.7, 5.6, 5.2, 5.8, 5.4 from least value to the greatest value that is 0.7, 3.1, 4.3, 5.2, 5.3, 5.4, 5.6, 5.8, we see that there is a large change in the value of the median from 0.7 to 3.1 as compared to rest of the values.
Median of 0.7 and 3.1 is =
, while median of rest of the data points are nearly same.
Thus, the outlier will be 0.7.

Answer: 78 ounces of dough was bought.
52 ounces of sauce was bought.
There were 13 guests .
Step-by-step explanation:
Let x = Number of guests
As per given, For each person 6 ounces of dough and 4 ounces of sauce is required.
i.e. Total ounces of dough and sauce together required = 6+4=10
The dough and sauce is 130 ounces all together.
i.e.
Divide both sides by 10 , we get
x= 13
i.e. there were 13 guests .
Total ounces of dough = 6 x ( Number of guests) = 6 x 13= 78 ounces
hence, 78 ounces of dough was bought.
Total ounces of sauce = 4 x ( Number of guests) = 4 x 13= 52 ounces
hence, 52 ounces of sauce was bought.
