Answer:

Step-by-step explanation:



because it's a straight angle(180)
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:
The ratio that compares the championships won by Australia to the total number won by the United States is equal to 
Step-by-step explanation:
Observing the graph
we know that
The championships won by Australia are 6
The championships won by the United States are 15
To find out the ratio, divide the championships won by Australia by the total number won by the United States.
so

Simplify
Divide by 3 boths (numerator and denominator)

Convert to percentage

that means
For every 2 championships won by Australia the United States won 5
or
The championships won by Australia are 40% of the championships won by the United States
