6) Some people think that ohemisits are more ilkely than other parents to have female children. The Washington State Dept of Heath lists the parents occupations on birth certificates. Between 1980 and 1990, 555 chiliren were bom to lathers who were chemists of these biths, 273 were girts. During this period, 48.8% of all births in Washingtion State were girls. Is there evidence at a significance level of 0.05 , that the proportion of girls bom to chemists is higher than the state proportion?±2⋅585.49(1−.49)p^=313173−7.49±2⋅.0217) You are told that the population mean score on a recent Calculus test is 59.5 out of 100 point You can't believe that and think it should be higher. You take a sample and find that in a sample 118 students, their mean score was 65.4 with a standard deviation of 20.8 . Run a hypothesis te significance level of 0.03 . Be sure to include your test statistic and p-value and interpret you results.a. . .03

Calculate standard error: Calculate the standard error using the formula for the standard error of a proportion: SE=p(1−p)/n, where p is the state proportion of girls, and n is the number of children born to chemists.SE=0.488(1−0.488)/555
