You are conducting a survey on the number of pets per household in your region. from a sample with n = 40, the mean number of pets per household is 2 pets and the standard deviation is 1 pet. using chebyshev's theorem, determine at least how many of the households have 0 to 4 pets.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

Write the pair of fractions as a pair of fractions with a common denominator

Would love some on this! include step by step have a good day!
