Question A police officer claims that the proportion of drivers wearing a seat belt in a certain area is less than 40%.
To test this claim, the officer collects a random sample of 80 drivers and monitors if the driver was wearing a seat belt.
From this sample of 80 drivers, the police offers observes that 34 were wearing seat belts.
Assume the conditions needed to conduct a one sample proportion test are satisfied.
The setup for the null and alternative hypothesis is as follows:
H : p = 0.40; H, :p < 0.40, which is a left-tailed test.
Compute the test statistic and p-value for this Hypothesis test using Excel and round your answers to 3 decimal places.

0.456

0.324

Explanation:

The null and alternative hypothesis :

H0 : p = 0.40; HA :p < 0.40

Test statistic :

(Ph - P) / sqrt[(p*(1-p))/n]

Ph = X / n

X = 34 ; n = sample size = 80

Ph = 34 / 80 = 0.425

(0.425 - 0.4) / sqrt[(0.4(0.6)) / 80]

0.025 / sqrt(0.003)

0.025 / 0.0547722

Test statistic = 0.4564359

Test statistic = 0.456

Using the P-value from Zscore calculator :

Significance level of 95% ; one tailed

Z statistic value = 0.456

P value = 0.324195

= 0.324 ( 3 decimal places)

with such great emphasis put on the act and sat exams—the studying, the review sessions, taking the test, retaking the test, scholarships dependent on scores, etc.—many think the scores are the be all end all of college applications. if you have a high score, you can get into any college you want. if you have a low score, you’re doomed.

answer: compare a myth legend, or classic work of literature of you choice to a modern work that reinterprets it.focus on the similarities in theme between the newer work and the original, and provide examples that illustrate these themes from both works. the modern work may be any novel, movie, play, short story, or other storytelling medium with which you’re familiars long as it is clearly inspired by a myth, legend, or classic work of literature.

short-response prompt  

read the following excerpt from “fish cheeks” by amy tannin which tan recounts a christmas eve dinner.  

i fell in love with the minister’s son the winter i turned fourteen. he was not chinese, but as white as mary in the manger. for christmas i prayed for this blond-haired boy, robert, and a slim new american nose.  

on christmas eve i saw that my mother had outdone herself in creating a strange menu. she was pulling black veins out of the backs of fleshy prawns. the kitchen was littered with appalling mounds of raw food: a slimy rock cod with bulging fish eyes that pleaded not to be thrown into a pan of hot oil. tofu, which looked like stacked wedges of rubbery white sponges. a howl soaking dried fungus back to life. a plate of squid, their backs crisscrossed with knife markings so they resembled bicycle tires.  

after everyone had gone, my mother said to me. “you want to be the same as american girls on the outside.” she handed me an early gift. it was a miniskirt in beige tweed. “but in side you must always be chinese. you must be proud you are different. your only shame is to have shame.”
