B) 9500
C) 200
D) 0.325
E) 3088
Step-by-step explanation:
A) The population of this survey is the registered voters in the city of Raleigh.
B) Population size can be defined as the total number of individuals in a population. Here the total number of individuals are the registered voters in the city. Therefore the size of the population is 9500.
c) Sample size is defined as the number of individual samples in a statistical test. Here the sample size is the 200 randomly selected registered voters. It is denoted as "n".
d) The sample statistic for the proportion of voters surveyed who said they'd vote for Brown would be:
p' = voters for brown / sample size

The sample statistic for the proportion of voters surveyed who said they'd vote for Brown is 0.325
E) The expected number of voters for Brown based on the sample:
0.325 * 9500 = 3087.5
Approximately 3088
The expected number of voters for Brown based on the sample might be 3088 voters.
6.292
1kg=9.69
1000g=9.68
650= 9.68/1000x650=0.00968x650
=£6.292
Original price is the jeans = Rs450
Discount = 25%
Discount amount
= 25% of 450
= 25%(450)
= 25/100 × 450
= 25/10 × 45
= 5/2 × 45
= 225/2
= Rs112.5
Price after discount
= original price - discount amount
= 450 - 112.5
= Rs337.5
