Hello all,
I have 24 means:
{79.2834, 74.4719, 73.8007, 73.5467, 72.2965, 76.136, 75.1637, 74.341,
75.7873, 75.997, 73.6585, 75.1196, 76.3168, 73.8244, 75.4527, 76.4404,
75.0104, 76.5596, 76.2118, 75.8198, 72.9094, 75.9392, 77.5203, 73.8933}
with associated 90% confidence intervals:
{{71.5152, 75.6588}, {71.1603, 75.3777}, {72.2091, 76.9714}, {72.4496,
77.0188}, {74.7051, 78.4491}, {72.1719, 76.8556}, {72.2981,
77.7783}, {72.5936, 76.9063}, {74.3673, 78.4631}, {73.9854, 78.8609},
{74.6407, 77.7396}, {73.9558, 77.9133}, {72.2582,
76.3498}, {73.2699, 78.5874}, {71.4071, 77.1258}, {75.7951, 80.7734},
{74.3078, 78.3051}, {71.2209, 76.5365}, {70.7587,
76.3733}, {73.8667, 78.1864}}
I also have a reference mean:
75.7718
I would like to plot the reference mean with a confidence interval of 80%
and 125%, next to the 24 samples, as a bar chart with 'error bars'
representing the confidence intervals.
Does anyone know how this can be done?
TIA,
Judy
