Abstract:
This study investigated whether sexual intercourse during pregnancy is associated with spontaneous preterm birth (SPTB). We included 77 women with SPTB and 145 women with a term birth. A total of 195 (87.8%) women had sexual intercourse during pregnancy, which was comparable between the groups. Primiparas with SPTB tended to report more often having sexual intercourse 3 - 4 times a week compared to primiparas with a term birth (8.8% vs. 0%, p =.082). We advise not to completely discourage sexual intercourse among pregnant women. Yet, high sexual intercourse frequency could be associated with SPTB.

Testing a Claim about Mean: Known Population SD
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
