Answer:
A. 0.0049
B. Yes
Step-by-step explanation:
Sample proportion = 0.64
N = 1000
Population proportion = 0.60
We solve for standard deviation
= √p(1-p)/n
= √0.60(1-0.60)/1000
= √0.60x0.40/1000
= √0.00024
= 0.0155
A.
The probability of sample >=0.64
Z>=0.64-0.60/0.0155
Z >= 0.04/0.0155
So z >= 2.5806
Using excel this equal to 0.0049
0.0049 is probability of sample proportion being 0.64 at least.

Assuming Mark wants to buy a PS5 for $499.00 and the tax in her local county is 7.75% of the total sale, what will be the final cost is $538
Using this formula
Final cost =Total sales+ (Total sales×Tax)
Let plug in the formula
Final cost= $499.00+($499.00×7.75%)
Final cost= $499.00+$38.67
Final cost= $537.67
Final cost= $538 (Approximately)
Inconclusion Assuming Mark wants to buy a PS5 for $499.00 and the tax in her local county is 7.75% of the total sale, what will be the final cost is $538
