In practice, the most frequently encountered hypothesis test about a population variance is a

a. two-tailed test, with unequal-size rejection regions

b. one-tailed test, with rejection region in lower tail

c. two-tailed test, with equal-size rejection regions

d. one-tailed test, with rejection region in upper tail

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

i hope that is right.

step-by-step explanation:

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.

i believe your answer is a
