The average monthly rent for one-bedroom apartments in New York has been $900. Becauseof the inflation in the housing market, it is believed that there has been an increase in theaverage rental. The correct hypotheses to be tested areHo: μ ≥ 900Ho: μ = 900Ho: μ > 900Ho: μ < 900Ha: μ< 900.Ha: μ # 900.Ha: μ = 900.Ha: μ> 900.

In a study of 48 cases of a certain diseases, it was noted that 17 cases developed complications, a frequency of 35%. a. Within the limits, would you expect the true frequency of complications in such cases to be contained? b. Suppose that you observed 170 complications in 480 cases, within what limit would you expect the true frequency of complication in such cases to be contained? c. How do you explain the difference between a and b?

To test this claim, a random sample of 35 human subjects were tested and it was found out that their average resting heart rate is 87 beats per minute (bpm). Studies suggest that the average resting heart rate of a normal adult is around 80 beats per minute (bpm) with a standard deviation of 20 beats per minute (bpm). Which of the conclusion is supported by the data at 0.01 level of significance? a. The vaccine does not significantly increase the average resting heart rate. b. There is no sufficient evidence to say that the vaccine significantly increase the average resting heart rate. c. The vaccine…
