When we have a significant result that means where represent the p value for the test and the significance level assumed at the begin of the hypothesis test.
For this case we have a null hypothesis and an alternative hypothesis for a parameter of interest let's say , and using the test we conclude thar we reject the null hypothesis, so on this case we need to have that , so then that means that we have a significant difference.
And when we have this situation we can't say that the difference between the sample statistic and the hypothesized parameter is just due to chance, since we are obtaining singificant results that are showing difference between the two values on statistical terms

Step-by-step explanation:
Step-by-step explanation:
A playing card is in the form of a rectangle whose perimeter is equal to 28 cm and area is 45 cm².
If l and b are length and breadth of the rectangle.
Area,
Perimeter,
Put the value of l from equation (1) to equation (2). So,
Put the value of b in equation (1),
If b = 5 cm
If b = 9 cm
So, the dimensions of the playing card is 9 cm by 5 cm.
