Answer:
: p= .78
: p > .78
Step-by-step explanation:
Determining the null and alternate hypotheses of a scenario require several components. The first is if one should use p or mu. This depends on if they are assessing a proportion or a mean, since the publisher states a percentage, you know that they are asking for a proportion, and therefore should use p. Next, they will need to assess what value to use for the hypothesis statements, here only .78 is provided and therefore should be used in both. Finally, it is time to add in the comparison symbols, the null hypothesis always uses an equals sign so it therefore becomes:
: p= .78
The alternate hypothesis then needs to consider if the researchers claim that the new proportion is greater, fewer, or different. In this case it is greater as they think that the ownership is above 78%, so a greater than sign would be used and the final statement would be:
: p > .78

Step-by-step explanation:
x > 3 reads x is greater than three. This includes all numbers to the right of three, but not three itself. |₋₋|₋₋|₋₋₀---|---|---|---|---|---|----->

x ≤5 reads x is less than or equal to five. This includes all numbers to the left of and including the number 5 <--|---|---|---|---|---|---|--•₋₋₋|₋₋|₋₋₋|₋₋₋|₋₋₋₋

x ≥ -4 reads x is greater than or equal to minus four. This includes all numbers to the right of and including -4.
