Fifty-three percent of U.S households have a personal computer. In a random sample of 250 households, what is the probability th

aleksley [76]

Answer:

The correct Answer is 0.0571

Explanation:

53% of U.S. households have a PCs.

So, P(Having personal computer) = p = 0.53

Sample size(n) = 250

np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10

So, we can just estimate binomial distribution to normal distribution

Mean of proportion(p) = 0.53

Standard error of proportion(SE) = $\sqrt{\frac{p(1-p)}{n} }$ = $\sqrt{\frac{0.53(1-0.53)}{250} }$ = 0.0316

For x = 120, sample proportion(p) = $\frac{x}{n}$ = $\frac{120}{250}$ = 0.48

So, likelihood that fewer than 120 have a PC

= P(x < 120)

= P( p^ < 0.48 )

= P(z < $\frac{0.48-0.53}{0.0316}$ ) (z= $\frac{p^-p}{SE}$ )

= P(z < -1.58)

= 0.0571 ( From normal table )

Write a program that generates 1,000 random integers between 0 and 9 and displays the count for each number. (Hint: Use a list o

masya89 [10]

Answer:

import random

count0, count1, count2, count3,

count4, count5, count6, count7,

count8, count9, i = [0 for _ in range(11)]

while i < 1000:

number = random.randint(0,9)

if number == 0:

count0 = count0 + 1

if number == 1:

count1 = count1 + 1

if number == 2:

count2 = count2 + 1

if number == 3:

count3 = count3 + 1

if number == 4:

count4 = count4 + 1

if number == 0:

count5 = count5 + 1

if number == 6:

count6 = count6 + 1

if number == 7:

count7 = count7 + 1

if number == 0:

count8 = count8 + 1

if number == 9:

count9 = count9 + 1

i = i+1

print("0's: "+ str(count0) + "\n"+ "1's: "+ str(count1) + "\n"+

"2's: "+ str(count2) + "\n"+ "3's: "+ str(count3) + "\n"+

"4's: "+ str(count4) + "\n"+ "5's: "+ str(count5) + "\n"+

"6's: "+ str(count6) + "\n"+ "7's: "+ str(count7) + "\n"+

"8's: "+ str(count8) + "\n"+ "9's: "+ str(count9) + "\n")

Explanation:

- Initialize variables to hold the count for each number

- Initialize i to control the while loop

- Inside the while loop, check for the numbers and increment the count values when matched.

- Print the result

favorite_color = input("Enter favorite color:\n")

pet = input("Enter pet's name:\n")

print("First password: "+password1)

print("Second password: "+password2)

print("Number of characters in "+password1+": "+str(len(password1)))

print("Number of characters in "+password2+": "+str(len(password2)))

This works for me.
