29) a g. p. bulk bills at $41.20 per consultation, and sees a new patient every 15 minutes for 3 hours. a new employee calculates the number of patients and then calculates the medicare bill as follows:

number of patients: 3 ÷ 0.15 = 20
medicare bill: 20 × $41.20 = $ 824

a) identify and describe the error.



b) recalculate the medicare bill







c) discuss the possible outcomes if this error occurred in real life, for the g. p. and for medicare.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
