Answer:
it is B, i did this question
Explanation:
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:
The correct answer to the following question will be "Smoking".
Explanation:
- Smoking will also be the "big or great equalizer" for women who have suffered from heart failure. Men typically get a much-increased chance of developing heart problems among non-smokers versus girls who haven't already infertile.
- Part of the whole success might be attributed to robust public awareness initiatives aimed at educating people about cigarette smoke's toxic contaminants and stopping teenagers from ever becoming addicts.
Just over 50 percent of adult Americans engage in aerobic physical activity that meets the national guidelines.
More about aerobic physical activity:
Exercise that relies primarily on the aerobic energy-generating mechanism is known as aerobic exercise, often known as endurance exercises, cardio, or cardio-respiratory exercise.
According to the dictionary, the term "aerobic" refers to the use of oxygen to appropriately provide the energy demands of aerobic metabolism during activity.
Benifits of aerobic physical activity:
- Increases the strength of the breathing muscles to make it easier for air to enter and exit the lungs.
- Increases blood flow efficiency and lowers blood pressure
- Increases sensitivity to pain
- Keeps independence during old age
