Transcribed Image Text:**Pulse Rates Analysis (Beats Per Minute)**
This data presents pulse rates, measured in beats per minute, for two groups, Males and Females. The pulse rates are listed in columns under each group.
**Males:**
- 81, 76, 52, 62, 55, 61, 53, 77, 52, 63
- 74, 59, 61, 76, 81, 64, 66, 94, 45, 83
**Females:**
- 75, 62, 70, 71, 55, 65, 58, 78, 70, 63
- 64, 98, 56, 66, 56, 55, 68, 71, 85, 58
**Females (continued):**
- 81, 94, 59, 63, 55, 82, 77, 84, 59, 35
- 66, 86, 86, 77, 76, 64, 69, 77, 61, 66
**Females (continued):**
- 86, 82, 71, 74, 85, 92, 89, 90, 59, 66
- 85, 82, 94, 54, 98, 73, 76, 77
This data can be used for comparative studies of average pulse rates between genders, or for statistical analysis such as finding means, medians, and ranges for each gender group. The variability in pulse rates can be further explored to understand factors affecting heart rates in different individuals.

*(Round to one decimal place as needed.)*
**Compare the results.**
- **A.** The confidence intervals overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
- **B.** The confidence intervals do not overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males.
- **C.** The confidence intervals do not overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
- **D.** The confidence intervals overlap, so it appears that adult males have a significantly higher mean pulse rate than adult females.](https://content.bartleby.com/qna-images/question/121bf263-4a6e-46d9-9385-c90d802499da/861d99f8-6ce1-4af9-82ba-dcbd6b7ae5d0/tyvpawt_processed.jpeg)
