Hi, can I get the answers for these questions please?

2} Question 28 1 pts Sample Size Calculations A researcher wants to design an experiment comparing a treatment group to an control group. The researcher is evaluating the effect of a new drug on systolic blood pressure {58?}. The researcher estimates the standard deviation of SEP in the population to be 10 mmHg. The drug is estimated to decrease ESP by 5 mmHg on average. What is the total sampie size required to detect this effect with 80% power? Assume SBF' is apprcnrimateh.i normally distributed in the population. } Question 29 1 pts What is the total sample size required to detect this effect with 90% power? } Question 30 1 pts What is the total sample size required to detect a difference of 10 mmHg with 80% power? D Question 30 1 pts What is the total sample size required to detect a difference of 10 mmHg with 80% power? D Question 31 1 pts Assume the expected difference is back to 5 mmHg, but the sample sizes for the two groups will be unequal. Twice as many.Ir people will be allocated to the treatment group compared to the control group. What is the total sample size required to achieve 30% power
