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:
Using an inverse normal table, and halving
for a two-tailed test, we look up 
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◦.

Answer:
Predicted Rotten Tomatoes Score = 29.476 + 1.201 * Metascore
Step-by-step explanation:
The image is needed to solve it, I found an image that I think would be the one that adapts to the exercise, which I will attach.
The answer is:
Predicted Rotten Tomatoes Score = 29,476 + 1,201 * Metascore
Because if we follow the red line, we can see that it impacts with the axis of the and a little lower than 30, that is to say that when Metascore is 0, the value must be close to 30 and in this case the only value close to 30 inside the answer is 29,476, so this is the answer.
