A culture started with 6,000 bacteria. After 8 hours, it grew to 8,262 bacteria.
Using the exponential growth formula,
P= Aext estimate how many bacteria
will be present after 24 hours.
A = 6,000 t = 24 k = 0.0400

step-by-step explanation:

sry but any answer choices

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;

its   c, f, a
