Answer:
390 ft²
Step-by-step explanation:
25x10= 250
20x7= 140
250+140= 390
567 would round out to 600. If you are also rounding the three, then that is one. The answer to that would be 600. If you aren't rounding the three, the answer would be 1800.
Answer:
Type I error : Option A
Type II error : Option C
Step-by-step explanation:
We are given that the percentage of households with Internet access is greater than 60%.
So, Null hypothesis, : p = 60%
Alternate Hypothesis, : p > 60%
Now, <u>Type I error states that</u> : Probability of rejecting null hypothesis given the fact that null hypothesis was true.
So, in our question Type I error will be Rejecting the null hypothesis that the percentage of households with Internet access is equal to 60% when that percentage is actually equal to 60%.
Now, <u>Type II error states that</u> : Probability of accepting null hypothesis given the fact that null hypothesis was false.
So, in our question Type Ii error will be Failing to reject the null hypothesis that the percentage of households with Internet access is equal to 60% when that percentage is actually greater than 60%.
