An opinion poll asks an SRS of 1500 adults, "Do you happen to jog?" Suppose that the population proportion who jog (a parameter)

is p = 0.15. To estimate p, we use the proportion p-hat in the sample who answer "Yes." Justify the use of a normal approximation and find the following probabilities.
a) P(p > 0.16)
b) P(0.14

Answer:

0.14007 ; 0.71986

Explanation:

Given that :

Justification :

Mean = np ≥ 10

(1 - np) ≥ 10

n = sample size ; p = 0.15

q 1 - 0.15 = 0.85

np = 1500 * 0.15 = 225 > 10

nq = 1500 * 0.85 = 1275 > 10

Hence, the Justification

P(p" > 0.16)

P(Z > (p" - p) /sqrt(p(q) /n))

P(Z > (0.16- 0.15) /sqrt(0.15(0.85) /1500))

P(Z > 0.01 / 0.0092195)

P(Z > 1.08) = 0.14007

P(0.14 < p < 0.16)

P(Z (0.14- 0.15) /sqrt(0.15(0.85) /1500)) < Z < (0.16 - 0.15) /sqrt(0.15(0.85) /1500))

P(Z <-0.01 / 0.0092195) - 0.01 / 0.0092195)

P(Z < 1.08) - P(Z < - 1.08)

Using the Z probability m calculator :

0.85993 - 0.14007

= 0.71986

= 0.72208

I NEED THE SUMMMARY FOE THE ADVENTURE OF MONTGOMERY MAY
Vladimir [108]

For ten years, Montgomery May traveled the world in a battered old ship.

When he returned home, he told everyone about the adventures he’d had and

the feats he had accomplished.

One of his most renowned feats was a leap. “I leaped from the island of

Rhodes to the mainland of Turkey, the great sea nipping at my ankles the

whole way,” Montgomery boasted one day to a crowd in the town square.

“Hundreds of people saw me do it. I leaped a greater distance than any man

has ever leaped. Anyone who saw me would tell you so.”

Cecil Saunders, Montgomery’s old rival, smiled. “No need to wait for

those people, Montgomery,” he said. “Pretend you are in Rhodes and show us

how far you can jump.”

Montgomery paused for only a moment. “Gladly, Cecil. If it meets with

your approval, I shall leap from Partridge Point”—and here he pointed to a

rocky outcrop where his ship was anchored—“to Isla’s Island.”

Cecil peered at the black dot far out at sea. “Hmph. Not quite the distance

from Rhodes to Turkey, but I suppose it will have to do.”

“Tomorrow morning at 7 a.m. sharp,” said Montgomery. “But such a leap

requires considerable sustenance and ample rest beforehand.” He now raised

his voice to the crowd. “Who among you will fuel me to my success?”

The townspeople cheered and crowded around him, each competing to

feed and house such an honored guest for the night. After much

effort, the wealthiest man in town persuaded Montgomery to come

and sup and sleep at his home.

And that was how Montgomery May came to eat a rich meal

and sleep in a vast featherbed before sneaking out to his boat

at 6 a.m. and sailing into the sunrise—doubtless to have more

adventures and accomplish more feats.

When Ralphie, Randy, Flick, and Schwartz hear Scut Farkas’ laugh, they experience fear. Complete the diagram below for this exam
Alinara [238K]

The situation described is an example of classical conditioning because a stimulus (Scut Farkas laughs) causes a specific reaction (fear in the other characters)

<h3>What is classical conditioning?</h3>

Classical conditioning is a scientific theory that focused on the study of a type of associative learning developed by Ivan Pávlov.

Classical conditioning posits that an external stimulus can generate a specific response in an individual or group depending on whether it has associated both factors, for example:

  • A dog makes a response (in this case, salivation) to a stimulus (the bell indicating food). The next time he heard the bell, regardless of whether it was attached to the food, he would begin to salivate.

Based on the above, it can be inferred that the situation described is an example of classical conditioning because the characters associate Scut Farkas' laughter with a feeling of fear.
