Answer:
7 ; 19 ; 8% ; 28%
Step-by-step explanation:
Given the data:
791 542 671 672 555 582 616 961 639
691 648 967 959 826 573 598 790 954
711 515 649 960 949 802 507
How many of the 13-year-olds sent at least 600 but less than 700 text messages? = 7
c-2. How many sent less than 900 text messages? = (7 + 7 + 3 + 2) = 19
d-1. What percent of the 13-year-olds sent at least 800 but less than 900 text messages? =0.08 × 100 = 8% (from relative frequency)
d-5. What percent of the 13-year-olds sent less than 600 text messages? 0.28 × 100 = 28% (from relative frequency)
Answer:
ITS 21

Question Continuation
A customer who owns shares in just one fund is to be selected at random.
a. What is the probability that the selected individual owns shares in the balanced fund?
b. What is the probability that the individual owns shares in a bond fund
Answer:
a. 0.08
b. 0.28
Step-by-step explanation:
Given
Money-market 22%
High-risk stock 17%
Short bond 11%
Moderate-risk stock 25%
Intermediate bond 12%
Balanced 8%
Long bond 5%
a. What is the probability that the selected individual owns shares in the balanced fund?
Let P(Balanced) = The probability that the selected individual owns shares in the balanced fund
P(Balanced) is given as 8% from the above table
So, P(Balanced) = 8/100
P(Balanced) = 0.08
b. What is the probability that the individual owns shares in a bond fund
Let P(Bond) = The probability that the individual owns shares in a bund fund
P(Bond) = P(Short Bond) + P(Intermediate Bond) + P(Long Bond)
P(Short Bond) = 11%
P(Intermediate Bond) = 12%
P(Long Bond) = 5%
So, P(Bond) = 11% + 12% + 5%
P(Bond) = 28%
P(Bond) = 0.28
Answer:
$35
Step-by-step explanation:
divide 25 by 5 to get the unit rate and then take that and multiply that by 7
