Answer:
0.8686 or 86.86 %
0.2148 or 21.48 %
Step-by-step explanation:
In z table the value of z > - 1,12 is 0.1314 (value from the z point to the left of the curve ) then 1 - 01314 will be value from z point to the right
Again from z table we get for z = - 0.79 the value 0.2148 s the vale from the point up to the left tail

Answer:
Alternative hypothesis:
Or in the alternative way would be:
Alternative hypothesis:
Step-by-step explanation:
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
On this case the claim that they want to test is: "The means for the two groups (American Idol and 60 Minutes) is the same". So we want to check if we have significant differences between the two means, so this needs to be on the alternative hypothesis and on the null hypothesis we need to have the complement of the alternative hypothesis.
Null hypothesis:
This null hypothesis can be expressed like this:
Null hypothesis:
Alternative hypothesis:
Or in the alternative way would be:
Alternative hypothesis:
Jessica is purchasing a new car whose MSRP is $19,750. She is trading in her old car for $8100.
Without the upgrade package and delivery charge , the cost of her car is
19,750 - 8100 = $11650
upgraded cost = $6000 and Vehicle delivery = $600. we add the upgraded cost and delivery cost.
Total cost of car = 11650 + 6000 + 600 = $18,250
