The family of poison dart frogs (Dendrobatidae) boasts over 245 species, displaying an astonishing array of colors and potency. The brilliant colors and patterns range from strawberry red, canary yellow, and sunny orange to metallic green and black with yellow polka-dots. When eaten, some merely taste bitter or irritate the predator’s mouth with burning or numbness; a few, however, are truly deadly, even to humans. the Golden poison frog is <span>the deadliest animal on land(poison wise) but the Black-legged poison frog is right up there next to it. both can easily kill a human. Though no deaths have been confirmed, the Kokoe poison frog can theoretically also kill a human, it is just as toxic as the black-legged poison frog. so what do they all have in common? they can all kill humans

i hope this helps, please give me brainliest </span>

Answer:

Car were more expensive in 2011

Explanation:

Data provided in the question:

Mean price of the car in 1965 = $2,650

Standard deviation, s = $1,000

Mean price of the car in 2011 = $30,500

Standard deviation in 2011, s = $9,000

Cost in 1965 = $2,300

Cost in 2011 = $28,000

Now,

z score = [ X - mean ] ÷ s

Therefore,

In 1965

z score = [ $2,300 - $2,650] ÷ 1,000

= -0.35

In 2011

z score = [ $28,000 - $30,500 ] ÷ 9,000

= -0.278

Since,

The standard score in 2011 is higher than in 1965

Hence,

Car were more expensive in 2011
