According to a human modeling project, the distribution of foot lengths of women is approximately Normal with a mean of 23.2 centimeters and a standard deviation of 1.3 centimeters. Suppose a shoe store stocks shoes in women's sizes 5 through 9. These shoes will fit women with feet that are 21.6 to 25 centimeters long. What percentage of women will be able to find shoes that fit in this store? The percentage of women that will be able to find a shoe that fits in this store is ☐ %. (Round to one decimal place as needed.)
