So hmm let's say

t = number of movie tickets purchased
m = number of meals bought

so... he earns 0.5 for each ticket... so if he bought "t" tickets, he then earned 0.5*t or 0.5t , whatever that is

and if he bought "m" meals, since each one is $2 earnings, then he earned 2 * m or 2m, whatever that is

is just so happen, we know, for last month he earned on his rebates $25
thus

0.5t + 2m = 25

it just so happen we also know he bought 22 movie tickets last month
thus

\bf 0.5(22) + 2m = 25\implies 11+2m=25\implies 2m=25-11
\\\\\\
2m=14\implies m=\cfrac{14}{2}\implies \boxed{m=7}

A student researcher compares the heights of American students and non-American students from the student body of a certain coll
Nonamiya [84]

Answer:

The 90% confidence interval for the difference between means is (4.189, 8.011).

The point estimate is the difference between sample means and has a value of Md=6.1.

Step-by-step explanation:

We have to calculate a 90% confidence interval for the difference between means.

The sample 1 (American students), of size n1=12 has a mean of 69.4 and a standard deviation of 2.79.

The sample 2 (non-American students), of size n2=17 has a mean of 63.3 and a standard deviation of 3.22.

The difference between sample means is Md=6.1.

M_d=M_1-M_2=69.4-63.3=6.1

The estimated standard error of the difference between means is computed using the formula:

s_{M_d}=\sqrt{\dfrac{\sigma_1^2}{n_1}+\dfrac{\sigma_2^2}{n_2}}=\sqrt{\dfrac{2.79^2}{12}+\dfrac{3.22^2}{17}}\\\\\\s_{M_d}=\sqrt{0.649+0.61}=\sqrt{1.259}=1.12

The critical t-value for a 90% confidence interval is t=1.703.

The margin of error (MOE) can be calculated as:

MOE=t\cdot s_{M_d}=1.703 \cdot 1.12=1.911

Then, the lower and upper bounds of the confidence interval are:

LL=M_d-t \cdot s_{M_d} = 6.1-1.911=4.189\\\\UL=M_d+t \cdot s_{M_d} = 6.1+1.911=8.011

The 90% confidence interval for the difference between means is (4.189, 8.011).
