Statistics and probability To determine her heart rate, Charlotte divides up her day into three parts: morning, afternoon, and evening. She then measures her heart rate at 3 randomly selected times during each part of the day.**What type of sampling is used?**- A. Stratified- B. Cluster- C. Convenience- D. Systematic- E. Simple randomThis question is designed to test the understanding of different sampling methods. Here, the key is in recognizing that Charlotte's approach involves dividing the day into specific segments (morning, afternoon, and evening) and then taking random measurements within each segment. This suggests the use of stratified sampling, where the population is divided into strata (in this case, time segments), and random samples are taken from each stratum.

Number of Multiplee The data on the right represent the number of live multiple-delivery births (three or more babies) in a particular year for women 15 to 54 years old. Use the data to complete parts (a) through (d) below. Age Births 15-19 95 20-24 508 25-29 1622 30-34 2835 35-39 1843 40-44 377 45-54 117 (a) Determine the probability that a randomly selected multiple birth for women 15-54 years old involved a mother 30 to 39 years old. P(30 to 39) = 0.632 (Type an integer or decimal rounded to three decimal places as needed.) (b) Determine the probability that a randomly selected multiple birth for women 15-54 years old involved a mother who was not 30 to 39 years old. P(not 30 to 39) = 0.368 (Type an integer or decimal rounded to three decimal places as needed.) %D (c) Determine the probability that a randomly selected multiple birth for women 15-54 years old involved a mother who was less than 45 years old. P(less than 45) = 0.984 (Type an integer or decimal rounded to three decimal…
