Horseshoe crabs on a beach can be overturned by approaching waves. These “stranded” crabs may right themselves by turning over. During a period of many days on an Atlantic Ocean beach, investigators categorized a random sample of crabs as either stranded or not stranded and additionally noted their age category. The researchers wanted to investigate whether there is convincing evidence of an association between becoming stranded and age. Data from their study are shown in the following table. Horseshoe Crab Stranded Status Young Intermediate Adult Total Yes 41 125 52 218 No 153 364 70 587 Total 194 489 122 805 If becoming stranded and age are independent in these creatures, which of the following is closest to the expected number of young stranded horseshoe crabs?
