According to a recent study, the carapace length for adult males of a certain species of tarantula are normally distributed with a mean of mu equals 18.45μ=18.45 mm and a standard deviation of sigma equals 1.63σ=1.63 mm. Complete parts (a) through (d) below.
a. Find the percentage of the tarantulas that have a carapace length between 15 mm and 16 mm. The percentage of the tarantulas that have a carapace length between 15 and 16 is %. (Type an integer or decimal rounded to two decimal places as needed.)
b. Find the percentage of the tarantulas that have a carapace length exceeding 18 mm. The percentage of the tarantulas that have a carapace length exceeding 18 is %. (Type an integer or decimal rounded to two decimal places as needed.)
c. Determine and interpret the quartiles for the carapace length of these tarantulas. The first quartile is. (Type an integer of decimal rounded to two decimal places as needed.)
