Answer and Step-by-step explanation:
The data represent sample of five men and five women conducted a randomization test to compare the sexes on the variable pulse.
The samples revealed that in 120 out of 252 possible outcomes under randomization have large difference. From this information it cannot be concluded that the sexes differ with regard to pulse.
The hypothesis test should be conducted between treatment and response for valid conclusion. The student can consider the biological content of men and women or verbal statements. The answer varies from person to person according to their respective data set. Therefore, it cannot be concluded that the sexes differ with regard to pulse.
First convert the distance to miles
<span>9.5 × 10^12 km x 0.62 miles/km </span>
<span>= (0.62 × 9.5) x 10^12 miles </span>
<span>= 5.9 × 10^12 miles </span>
<span> we want to triple that, because it is 3 light years (not just 1): </span>
<span>3 x 5.9 × 10^12 miles </span>
<span>≈ 18 × 10^12 miles </span>
<span>≈ 1.8 × 10^13 miles </span>
<span>Next divide by the speed to get the time (in hours). </span>
<span>t = 1.8 × 10^13 miles / 17000 miles/hour </span>
<span>convert the speed to scientific notation: </span>
<span>t = 1.8 × 10^13 / 1.7 x 10^4 </span>
<span>t = (1.8 / 1.7) × (10^13 / 10^4) <-- when dividing powers with the same base, subtract the exponents </span>
<span>t ≈ 1.1 × 10^9 </span>
<span>convert that back to standard notation. </span>
<span>Answer: </span>
<span>1,100,000,000 hours (P.S. That is about 120,000 years).
Hope this helps!!!</span>
