The average age for menopause for women in the UK is 51.21 years. A pharmaceutical company wants to test a new medication to see if it has any effect on the average age of menopause. A random sample of 400 participants who have taken the medication has a mean of 56.45 and standard deviation of 12.6. Did the medication affect menopause? You can use the z-table supplied below. a) ull and alternative hypotheses. b) Calculate the Z score which is required to achieve a confidence level of 95% for a Normal Z ution. At a 95% confidence level, is there enough evidence to support that the medicine works wit a significant effect? Express what null and alternative hypothesis are here. You must show your calculation, draw the Z-normal curve and indicate where value of the Z must lie to accept or reject the null hypotheses.
