Kaitlin will spend less than $29 on gifts. So far, she has spent $17. What are the possible additional amounts she will spend?

The possible additional amounts she will spend is less than 12

Solution:

Given that,

Kaitlin will spend less than $29 on gifts

So far, she has spent $17

Let "x" be the remaining amount she will spend

From given,

Remaining amount she can spend will be less than 29 - 17

Therefore,

Thus the possible additional amounts she will spend is less than 12

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;
