Idk I think it's either 0.4 or 1.3
The mean daily high temperature of Sample 2 is 84.8ยฐF.
The mean daily high temperatures of the two samples differ by 0.5ยฐF.
Sample 1: (78 + 82 + 85 + 87 + 90 + 85 + 79 + 86 + 91 + 88) / 10 = 85.1ยฐF
Sample 2: (81 + 79 + 80 + 86 + 89 + 92 + 82 + 88 + 84 + 87) / 10 = 84.8ยฐF
The mean daily high temperature of Sample 1 is 85.1ยฐF.
The mean daily high temperature of Sample 2 is 84.8ยฐF.
The mean daily high temperatures of the two samples differ by 0.3ยฐF.
I hope this clarifies things. Let's calculate the means again without division by 10, since each sample consists of 10 daily high temperatures.
Sample 1: 78 + 82 + 85 + 87 + 90 + 85 + 79 + 86 + 91 + 88 = 851
Sample 2: 81 + 79 + 80 + 86 + 89 + 92 + 82 + 88 + 84 + 87 = 848
Now, we can find the mean by dividing each sum by 10:
Mean daily high temperature of Sample 1: 851 / 10 = 85.1ยฐF
Mean daily high temperature of Sample 2: 848 / 10 = 84.8ยฐF
The mean daily high temperatures of the two samples differ by 0.3ยฐF. Thank you for your patience, and I hope this clears up any confusion.
what is the answer
Therefore, the difference between the mean daily high temperatures of the two samples is 0.3ยฐF. Thank you for pointing out the error, the correct answer is now provided.
