Question

Refer to the accompanying data set and construct a 95​% confidence interval estimate of the mean pulse rate of adult​ females; then do the same for adult males. Compare the results.

Males : 86. 76. 49. 61. 55. 63. 53. 73. 53. 61. 74. 59. 63. 76. 85. 68. 63. 94. 41. 84. 74. 64. 69. 72. 55. 68. 58. 78. 69. 66. 64. 94. 56. 66. 60. 57. 68. 72. 87. 60.

Females: 81. 91. 60. 68. 57. 81. 78. 85. 85. 55. 37. 68. 82. 75. 77. 61. 68. 80. 58. 64. 82. 83. 72. 71. 86. 88. 86. 89. 91. 94. 67. 90. 82. 81. 74. 58. 99. 71. 76. 78.

Construct a 95% confidence interval of the mean pulse rate for adult females. (Round to one decimal)

Construct a 95% confidence interval of the mean pulse rate for adult males. (Round to one decimal

Compare the results.

A. 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.

B. The confidence intervals​ overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.

C. The confidence intervals do not​ overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males.

D. The confidence intervals​ overlap, so it appears that adult males have a significantly higher mean pulse rate than adult females.

Answer 1

Here is the data:-

CI for males:

CI for females:

C. The confidence intervals do not​ overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males.
