To estimate the mean score μ of those who took the Medical College Admission Test on your campus, you will obtain the scores of

pychu [463]

Answer:

Step-by-step explanation:

Let X be the SRS scores of students.

Given that X is normal with standard deviation about 6.5.

Mean difference = $|bar x-\mu|$ is desired

i.e. Z score should be $|z|$

Std error = std deviation of sample = 0.447

b) $z =2.95\\\frac{1.3}{s} =2.95\\s = 0.447\\6.5/\sqrt{n} =0.447\\n >193$

So std error must be 0.997 and sample size must be atleast 193 to get the difference of x bar and mu to lie within 1.3 points in either direction

225 grams of flour are needed to make 9 cakes.

Brut [27]

So basically, 9 cakes need 225 grams of flour
Therefore 1 cake needs: $\frac{225}{9}$ = 25 grams of flour

Moreover, 20 cakes need: 20 × 25 = 500 grams of flour

500 g > 475 g

Marian does not have enough flour to make 20 cakes
