Answer:
We have sufficient evidence to conclude at α = .05 that the husband’s perception would be higher than the wife’s.
Step-by-step explanation:
The hypotheses testing procedure in the given scenario is
H0: Husband’s perception would be similar to the wife’s i.e. μh=μw
Ha: Husband’s perception would be higher than the wife’s i.e. μh>μw
Level of significance: α=0.05
Test statistic: t=2.776
Critical region: t>t(0.05,9)=1.833
Conclusion: As the calculated value of t lies in critical region, so we reject our null hypothesis at 0.05 level of significance. Thus, we have sufficient evidence to conclude at α = .05 that the husband’s perception would be higher than the wife’s.
Answer:
0.75 cents
Step-by-step explanation:
You take...
$2.25 and subtract $1.50 to get 0.75 cents
In-depth...
Start off with taking a dollar away...
2.25 - 1.00 = 1.25
Then take off 0.50 cents...
We know that 0.50 cents are two 0.25 cents
So, we take off one 0.25 cent
1.25 - 25 = 1.00
Then the next 0.25 cents
*Remember: twenty-five (.25), fifty (.50), seventy-five (.75), a dollar (1.00)
<--- it is just adding 25 each time
If we subtract 0.25 cents from a dollar we get...
0.75 cents
