the total number of fungal spores can be found using an infinite geometric series where a1 = 11 and the common ratio is 2. find the sum of this infinite series that will be the upper limit of the fungal spores.

465
280
the series is divergent
125

  The series is divergent

Step-by-step explanation:

An infinite geometric series with a common ratio greater than 1 does not converge to a sum. The series is divergent.

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;
