The distribution of weight of a small watermelon is known to have a mean of 5 pounds and a standard deviation of 1.2 pounds. Six small watermelons fit in a crate, and the crate weighs exactly 1 pound. Assuming the weights of small watermelons are independent, what is the standard deviation of the total weight of a random sample of 6 small watermelons and the crate? (A) √62(1.2)² (B) 1+ √√62(1.2)² (C) 1+62(1.2)2 (D) 6(1.2)² (E) 1+ √6(1.2)²
