Answer:
-6.134 to +6.134
Step-by-step explanation:
given that a large population of variable x is characterized by its known mean value of 6.1 units and a standard deviation of 1.0 units and a normal distribution
X is Normal with mean =6.1 and std dev = 1 unit
We are to determine the range of values containing 70% of the population of x
We know that normal distribution curve is bell shaped symmetrical about the mean.
So to find 70% range we can use 35% on either side of the mean
Using std normal distribution table the value of z for which probability from 0 to z is 0.35 is 1.034
Hence corresponding x value is

i.e. 70% values lie between
-6.134 to +6.134

Answer:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Step-by-step explanation:
Answer:
Coca Cola
Step-by-step explanation:
To find the unit price, divide the cost by the amount
Coca-Cola:
cost/amount
1.29/1.25=1.032
Rounded to the nearest cent: 1.03
Pepsi:
cost/amount
2.49/2=1.245
Rounded to the nearest cent: 1.25
So, Coca Cola is the better deal
Hope this helps! :)
