The hypothesis test:

Group of answer choices

has no tails

is two-tailed

is left-tailed

is right-tailed

The following are a random sample of adult ski sweater prices are from the Gorsuch Ltd. Winter catalog:

{$212, $292, $278, $199$280, $236}

Assume the underlying sweater price population is approximately normally distributed. A hypothesis test is done to determine whether the average price of all adult ski sweaters from Gorsuch Ltd. is at least $275.

The correct distribution to use for the hypothesis test is:

Group of answer choices

Binomial

Normal

Exponential

Student-t

The correct conclusion for this test is

Group of answer choices

he true average price of all adult ski sweaters in this catalog NOT more than $275.

The true average price of all adult ski sweaters in this catalog is less than $275.

The true average price of all adult ski sweaters in this catalog is more than $275.

The true average price of all adult ski sweaters in this catalog is $249.50

The true average price of all adult ski sweaters in this catalog is NOT less than $275.

In a two-tailed hypothesis test of the mean using a 0.05 level of significance, researchers calculated a p-value of 0.03. What conclusion can be drawn? The alternative hypothesis should be rejected because the p-value is so small. The null hypothesis is true because the p-value is less than the level of significance. The alternative hypothesis is 3% likely to be true. The null hypothesis should be rejected because the p-value is less than the level of significance. 1.The alternative hypothesis...
