I need help with statistics homework?

So this thing might cause miscarriages


It is known that the miscarriage rate of pregnancy under normal conditions is about 20%(i kno thats da norm)





In a survey of 697 female employees who used this thing, 145 had miscarriages happened





test to see if the rate has increased over that for normal conditions????








i dunno wat im supposed to do, normally we have data to use with this program called minitab, buuut not for this one

I need help with statistics homework?
If I understand correctly, this is just a matter of maths here.





Alright, do the following:





145/697





I worked out that this would make 0.208034433 which is 20.8%. So yes, it has increased by 0.8%





Is that what you meant?
