Detecting defects of tablets of drug M. suppose that probability of nodefects was found to be 20%. If 10 tablets were sampled,

Based on these information, answer question 14 and 15

14-What's the probability that the sample will exactly have 4 tablets with nodefects?

15-What's the probability that the sample will contain 5 or more tablets with nodefects?

16-The weights of aspirin tablets in a batch is normally distributed with mean of 600 mg and standard deviation = 90mg. What is the probability that a randomly selected tablet will have a weight more than 660 mg?

17-Discuss the types for sample bias in quantitative research

18-Discuss the normal distribution for data and implication for this in statistics?

19-Discuss how you determine sample size for a quantitative study.

20-Discuss the correlation between two variables
