Answer:
def replace_at_index(str, number):
new = str.replace(str[number], "-")
return new
print(replace_at_index("eggplant", 3))
Explanation:
- Create a function called <em>replace_at_index</em> that takes a string and an integer
- Initialize a new variable called <em>new</em>, that will hold the new string
- Replace the character at given index with dash using <em>replace</em> function, it takes two parameters: the first is the character we want to replace, the second is the new character.
- Return the new string
- Call the function with the required inputs

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) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
