A local company wants to evaluate their quality of service by surveying their customers. Their budget limits the number of surveys to 100. What is their maximum error of the estimated mean quality for a 93% level of confidence and an estimated standard deviation of 7? a. 1.8130 b. 1.1550 c. 1.2824 d. 1.3160

(C) 1.2824

Step-by-step explanation:

Maximum error = t × sd/√n

sd = 7

n = 1

degree of freedom = n - 1 = 100 - 1 = 99

confidence level = 93%

t-value corresponding to 99 degrees of freedom and 93% confidence level is 1.855

Maximum error = 1.855×7/√100 = 12.985/10 = 1.2985

The closest option is (C)

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
