Answer:
There are four forces of evolution: mutation, gene flow, genetic drift, and natural selection. Mutation creates new genetic variation in a gene pool. Gene flow and genetic drift alter allele frequencies in a gene pool

Answer:
Mean of sampling distribution=3.5
Standard error of sampling distribution=0.219
Explanation:
We know that
The average of catching fish per fishing trip=μ=3.5
and
The standard deviation of catching fish per fishing trip= σ=1.2.
We have to find the mean and standard error of sampling distribution of 30 fishing trips i.e. μxbar=? and σxbar=?
Mean of sampling distribution=μxbar=μ=3.5
Standard error of sampling distribution=σxbar=σ/√n
Standard error of sampling distribution=σxbar=1.2/√30
Standard error of sampling distribution=σxbar=1.2/5.4772
Standard error of sampling distribution=σxbar=0.219
Thus, the mean and standard error for a sampling distribution of 30 fishing trips are 3.5 and 0.219.
Answer:
b. Because they do not receive additional compensation through company benefits, contingent IT workers usually make less that full-time employees doing equivalent work.
Explanation:
- contingent workers are a group of people who do not have a clear definition of long-term employment with a company. His work is mainly based on short-term engagements.
- contingent workers do not receive salaries. Instead, they receive payment or commission for the work they do. They are not responsible for benefits such as contract employees and are responsible for their own taxes.
- so answer is b. Because they do not receive additional compensation through company benefits, contingent IT workers usually make less that full-time employees doing equivalent work.
