To find the mean, all we need to do is add up all the numbers then divide them by how many numbers there are

79 + 85 + 60 + 90 = 310

310 ÷ 4 = 77.5

Therefore the answer is %77.5

Hope this helps

What is normal, when it comes to people's body temperature? a random sample of 130 human body temperatures, provided by allen sh
nikitadnepr [17]
The two-sided alternative hypothesis is appropriate in this case, the reason being we are asked "does the data indicate that the average body temperature for healthy humans is different from 98.6◦........?".
The test statistic is:
Z= \frac{\bar{X}-\mu}{ \frac{s}{ \sqrt{n} } }} =-5.47
Using an inverse normal table, and halving \alpha for a two-tailed test, we look up p=0.5-\alpha/2=0.5-0.005=0.495 and find the critical value to be Z = 2.5758.
Comparing the test statistic Z = -5.47 with the rejection region Z < -2.5758 and Z > 2.5758. we find the test statistic lies in the rejection region. Therefore the evidence does not indicate that the average body temperature for healthy humans is different from 98.6◦.

igomit [66]
(4b+3) (2b−5)

(4b+3) (2b+−5)

(4b) (2b) + (4b) (−5) +(3) (2b) +(3) (−5)

8b²−20b+6b−15.

= 8b²−14b−15.
