soft drink manufacturer wishes to know how many soft drinks adults drink each week. They want to construct a 98% confidence interval for the mean and are assuming that the population standard deviation for the number of soft drinks consumed each week is 1. The study found that for a sample of 898 adults the mean number of soft drinks consumed per week is 6.4. Construct the desired confidence interval. Round your answers to one decimal place. Lower and high endpoint

Expert Solution
Solution :
Given that,
Point estimate = sample mean = 
= 6.4
Population standard deviation = 
= 1
Sample size = n = 898
At 98% confidence level the z is ,
= 1 - 98% = 1 - 0.98 = 0.02
/ 2 = 0.02 / 2 = 0.01
Z/2
= Z0.01 = 2.326
Margin of error = E = Z/2* ( /
= 2.326 * (1 /
= 0.1
At 98% confidence interval estimate of the population mean is,
- E < 
< + E
6.4 - 0.1 < < 6.4 + 0.1
6.3 < < 6.5
Lower endpoint = 6.3
High endpoint = 6.5

A soft drink manufacturer wishes to know how many soft drinks
teenagers drink each week. They want to construct a 90% confidence
interval with an error of no more than 0.07. A consultant has
informed them that a previous study found the mean to be 5.6 soft
drinks per week and found the standard deviation to be 1.4. What is
the minimum sample size required to create the specified confidence
interval? Round your answer up to the next integer.

Exhibit: Soft Drinks.
Last year, a soft drink manufacturer had 21% of the market. In
order to increase their portion of the market, the manufacturer has
introduced a new flavor in their soft drinks. A sample of 400
individuals participated in the taste test and 100 indicated that
they like the taste. We are interested in determining if more than
21% of the population will like the new soft drink at the
significance level 0.05.

Question 8
A soft drinks manufacturer produces a sports drink with an
'active ingredient' that supposedly has health benefits. The
quality control team is checking the amount of active ingredient in
the bottles of drink. From historical data, it is known that the
average amount () of active ingredient per bottle is 27
mg with a standard deviation of 0.707 mg.
Part a)
Calculate the probability that the amount of active ingredient
in a bottle is greater than 26 mg.

A distributor of soft drink vending machines knows from
experience that the mean number of drinks a machine will sell per
day varies according to the location of the machine. At a local

be two optimal locations (Location A and B). The number of drinks
sold per day for each machine is recorded for a random sample of 20
days. For each day, the number of drinks purchased at...
