Question 4 7.6923 point The average weight gain during pregnancy is normally distributed with a mean of 30 lbs and a population standard deviation of 8 lbs For a sample size of n=64 women who gave birth during the covid-19 pandemic stay at home order the average weight gain is 32 lbs. Use hypothesis testing whether the increase in weight gain for these women is statistically significance at the level of a=0.05 level. Ho is hypothesis that the mean weight gain of 30 is not statistically different than the increased sample weight gain a. P=0.0230.05 so it is unusual reject Ho O c. P=0.0230.05 so it is normal do not reject Ho A Moving to the next question prevents changes to this
