Respuesta :
The new mean of candies = 20 and the standard deviation is 12.
Given that,
Guests at a picnic try to guess the number of candies in a jar.
Mean = 85, standard deviation = 12
the jar actually holds 105 candies,
Want to convert each guess to its error, that is, we'll subtract 105 from each guess.
What is simplification?
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
What is Statistic?
Statistics is the study of mathematics that deals with relations between comprehensive data.
Since,
Mean = 85,
jar actually holds 105 candies
New mean = 105 - 85
= 20
Since,
When a certain value is subtracted from all the values standard deviation still remains the same.,so
Standard deviation = 12
Thus, the new mean of candies = 20, and the standard deviation is 12.
