Solution:

1.

Counting the number of people who have been exposed to the Zika virus is an example of which of the following?

ans: Discrete data

because number people counted as 1,2,3,.. hence this are Discrete data

2.Which type of bait catches the largest fish? A study was conducted using 3 different baits (worms, corn, and plastic lures), and the average weight of the fish caught was measured. What is the independent variable

Ans:The weight of the fish

Because if weight of fish is high then size of fish is big then size of fish is big means bit catches is large hence bit caches is dependent variable and weight of fish is independent variable

3.

Which type of bait catches the largest fish? A study was conducted using 3 different baits (worms, corn, and plastic lures), and the average weight of the fish caught was measured. What type of variable is the dependent variable?

Ans : Qualitative

Here dependent variable is type of bait catches and this are recorded as worms, corn, and plastic lures which is Quality data hence dependent variable is Qualitative .

4.

A study was conducted to determine if rats gain weight after experiencing different levels of exercise. Researchers used 24 rats, for three different levels of exercise, plus a control group. Rats were randomly assigned to each group until there were six rats per group. How many replications are there?

Ans : unanswered

because here three group are present and each having six replicate it means 3 * 6 = 18 replicates are there so we unanswered for this problem.

5.

Which of the following are true when using the stratified sampling method?

Ans:

All subjects have and equally likely chance of being selected

Subjects are selected from each strata

Strata are usually created by convenience

All subjects are measured in the selected strata

Here all options are correct

There has been an annual 3.1% prevalence of Zika virus in South American countries since 1947. Only 1% of all cases resulted in any DALY count (all cases, any year). In 2015, clinicians observed increased microcephaly among children born to women who had been ill from Zika within the last 12 months. A new screening test was developed with more sensitivity to understand the rate ofZika among women ages 20-35 in three South American countries. It can detect Zika in...

In a production plant, 20% people are exposed to very loud noises. Of those who are exposed to loud noises, 10% show sign of hearing loss at some point of their lives. Of those who are not exposed to loud noises, only 5% will develop hearing loss. a). What is the probability that a randomly chosen person is not exposed to loud noise? b). What is the probability that a randomly chosen person will experience hearing loss? c). Are the...

Most people who are infected with the HTLV-1 virus are asymptomatic carriers. One specific subtype of HTLV-I occurs only in a sub-population of the Japanese population and among the native peoples of the Andes mountain area of northern Chile. The researchers are looking for the presence of HTLV-1 DNA in the bone marrow cells of well-preserved Andean mummies. The presence of HTLV-1 DNA in the mummies, of the same subtype observed in Japan, would indicate that some of the first...
