The following observations are lifetimes (days) subsequent to diagnosis for individuals suffering from blood cancer. 116 182 256 418 442 461 516 739 743 789 808 866 924 984 1025 1062 1064 1166 1191 1222 1222 1252 1277 1291 1357 1369 1409 1455 1479 1519 1578 1578 1599 1604 1605 1697 1736 1799 1815 1852 1899 1925 1966
A) can a confidence interval for true average lifetime be calculated without assuming anything about the nature of the lifetime distribution? Explain.
B) Calculate and interpret a confidence interval with a 99% confidence level for true average lifetime.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

umm im not really sure because i never had to do this

step-by-step explanation:

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
