A park ranger fears that a harmful fungus might be infecting bluegill panfish in the parks lake. A fisherman offers to help the

ranger by catching a dozen bluegills from his favourite fishing spot on the lake and allowing the ranger to examine them for signs of the fungus. Would these 12 fish be a representative sample of the fish in the lake? Explain why or why not

Answer: No, not random. This is not a representative sample because the fish were all from the same location and thus not sufficiently random. Fish in one part of the lake may have the fungus, while fish in the other part may not.

Step-by-step explanation:

They are only getting it from the park rangers favorite spot rather than a variety of spots.

You are on a limited budget and planning a four day camping trip to a national park. bus fare is 75 dollars each way and the rid
Schach [20]

Considering that you are planning the trip with limited budget and only for 4 days (=96h) you must value both time and money when doing it.

If you use the bus you spend $75 + $75=$150 and 12h + 12h = 24h. This means you spend $150 to enjoy 96h - 24h = 72h of actually camping. This means you pay $150/72h = $2,08 per hour of actual camping.

On the other hand if you choose the plane you spend $150 + $ 150 = $300 and 1,5h + 1,5h = 3h. This means you spend $300 to enjoy 96h - 3h = 93h. This means you pay $300/93h = $3,22 per hour of actual camping.

Considering all that, taking the bus his the most cost-effective option (and the cheaper one also).
