Josh and Anthony have a lemonade stand.They charge $1 for 2 cups of lemonade.They sell 14 cups each afternoon.Is it reasonable t
Rudik [331]
No it is not, whatsoever.

$1 for 2 cups. 14 cups in an afternoon means they got $7. If they did this for three days (7 x 3) they'd have 21 dollars. it is not reasonable because 21 is nowhere near 50.

Hope this helps

given that a test statistic in a left tailed test is z equals -1.25, use a 0.05 significance level to find the p-value and state
mr Goodwill [35]

Answer:

The <em>p-</em>value of the test is 0.106.

The null hypothesis will be accepted at 5% level of significance.

Step-by-step explanation:

The hypothesis test is left-tailed.

The test statistic value is: <em>z</em> = -1.25.

The significance level of the test is: <em>α</em> = 0.05.

The <em>p</em>-value of a left-tailed hypothesis test is:

p-value=P(Z

The <em>p-</em>value of the test is 0.106.

**Use the <em>z-</em>table for the probability.

<u>Decision rule:</u>

If the <em>p</em>-value is less than the significance level the null hypothesis will be rejected and if it is more than the significance level the null hypothesis will be accepted.

The <em>p</em>-value = 0.106 > <em>α</em> = 0.05.

The null hypothesis will be accepted at 5% level of significance.
