Amir submersible is a type of submarine. as a mir dives below the surface, its
elevation changes by -100 feet each minute. from the surface, a mir takes about 200
minutes to reach the lowest point to which it can dive. what is its elevation at that
point?
step 1: write an integer that represents the change in elevation each minute.
step 2: write a product of integers that represents the total change in distance
after 200 minutes.
step 3: find the elevation of mir at its lowest point.

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;

hope this !
