Answer:
c. The Mean of Normal Distribution is related to the average of the data set. The Standard deviation is related to data variation.
Step-by-step explanation:
(a) No, mean don't tell us how much the data deviate from the average, Standard deviation tells us. So, Option (a) is incorrect.
(b) No, mean is greatly affected by extreme values. But Median is good to measure central tendency when there is outlier present in data. So, Option (b) is also incorrect.
(c) Here Mean and Standard deviation are correctly defined. Hence, this is only the correct answer.
(d) No, It is the definition of mean not of Standard Deviation. So, this option is also incorrect.
Further, Mean is used to measure the central tendency of data which represents the whole data in the best way. It can be found as the ratio of the sum of all the observations to the total number of observations.

Answer:
44 p points in 4 quarters = llets per Qtr.
Number 7 is a because line m crosses at 2 on the y axis and number 8 is a because it goes up by one half each time
Answer:
hey,its option a
Step-by-step explanation:
because angle F= angle M and angle G= angle L
and angle H= angle N
To know third angle in ∆HGF
,we know sum of all angles in a triangle is 180°
______________________________
let angle H be unknown value x
x+51+36=180
x=180-87 ---------------- 1
similarly in ∆MNL
let angle be y
51+36+y=180
y=180-87----------------2
_______________________________
From 1&2 we observe qngle x= angle y
