If the sales representative went to 300 schools in convinced 125 to sell their product what percentage decided not to sell their product round to the nearest 10th

58.3% decided not to buy this product.

Step-by-step explanation:

Use the word "buy" here, not "sell."

A.

Will buy product:  125 out of 300; percentage buying product is

125

= 5/12  =>  (5/12)(100%) = 41.7%

300

B Will not buy product:  100% less 41.7% (from above), or 58.3%

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

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;
