a.
To classify measurement as accurate precise, both or neither.
a.

Answer to Problem 1.5.2P
The set is neither accurate nor precise.
Explanation of Solution
Given information:
Set is 56.1 cm, 48.9 cm, 24.2 cm and 5 cm.
In the given set, the first two measurements are precise, but the next two are both even close. Hence, the set is neither accurate nor precise.
b.
To classify measurement as accurate precise, both or neither.
b.

Answer to Problem 1.5.2P
The set is neither accurate nor precise.
Explanation of Solution
Given information:
73.1 cm, 74 cm, 73.5cm and 73.7 cm.
In the given set, the values are not close. Hence, the set is neither accurate nor precise.
c.
To classify measurement as accurate precise, both or neither.
c.

Answer to Problem 1.5.2P
The given set is precise.
Explanation of Solution
Given information:
52.6 cm, 52.5 cm, 52.2 cm and 52.3
In the given set of measurement, each value is very close to the accurate measurement. Hence, the given set is precise.
d.
To verify the statement
d.

Answer to Problem 1.5.2P
The statement is correct
Explanation of Solution
Given information:
The statement
The word precision means “the quality, condition or fact of being exact and accurate.” It means if the measurement is accurate, it is also precise. Hence, the statement is correct

- Café Michigan's manager, Gary Stark, suspects that demand for mocha latte coffees depends on the price being charged. Based on historical observations, Gary has gathered the following data, which show the numbers of these coffees sold over six different price values: Price Number Sold $2.70 765 $3.50 515 $2.00 990 $4.30 240 $3.10 325 $4.00 475 Using simple linear regression and given that the price per cup is $1.85, the forecasted demand for mocha latte coffees will be cups (enter your response rounded to one decimal place).arrow_forwardGiven the correlation coefficient (r-value), determine the strength of the relationship.
