Answer:
1.80
Step-by-step explanation:
Since we're rounding up to 2 decimal places we won't put the 5 in 1.795 in consideration, we'll just round up 79 which will give us 80, so we'll have 1.80. We're not rounding up to the nearest whole number or to one decimal place so the answer will remain as 1.80
Answer:
b. A smaller sample size would increase the effectiveness of a hypothesis test.
Step-by-step explanation:
A hypothesis test is an important procedure in the field of statistics. It evaluates any two mutually exclusive statements about a population that determines and tells which statement made best supports to the sample data provided.
Now we know that an increase in the sample size makes the hypothesis test more effective and sensitive and it is more likely to reject the null hypothesis.
The probability of making a type I error is known as the Alpha while the probability of making type II error is called Beta.
Thus the correct option is (b).
22.83 would be rounded to 22.8 because 3 is lower than 5 so you keep the 8

For the second hour you add another 40 because 40 is the value for one hour and you need to know how many ropes in two hours. :) really hope this helps
