US National forest cover approximately 300,000 square miles. conversationalist want the total square footage of forests to be 30

0,000 (2nd power) square miles away. When I Vanna used her phone to do the calculation, her screen showed 9e+10. a what does the answer on her screen mean? Explain how you know b. Given that the US has approximately 4 million square miles of land, is this a reasonable goal for conversationalist? Explain

E+10 is equivalent to 10^10 so, 9e+10 is equivalent to 9*10^10. 300,000^2 is 90000000000 square miles, where as the US has 4000000. Therefore, if the national forest were as large as the environmentalist wants them to be, the forest would be larger than the US, which is IMPOSSIBLE !!! As a result, this goal is not reasonable

Answer:

(0,-5). y=mx+b or -5=0 × 0+b, or solving for b: b=-5-(0)(0). b=-5.

(2,-5). y=mx+b or -5=0 × 2+b, or solving for b: b=-5-(0)(2). b=-5.

y=-5

A customer service phone line claims that the wait times before a call is answered by a service representative is less than 3.3
Vika [28.1K]

Answer:

(A) Yes, since the test statistic is in the rejection region defined by the critical value, reject the null. The claim is the alternative, so the claim is supported.

Step-by-step explanation:

Null hypothesis: The wait time before a call is answered by a service representative is 3.3 minutes.

Alternate hypothesis: The wait time before a call is answered by a service representative is less than 3.3 minutes.

Test statistic (t) = (sample mean - population mean) ÷ sd/√n

sample mean = 3.24 minutes

population mean = 3.3 minutes

sd = 0.4 minutes

n = 62

degree of freedom = n - 1 = 62 - 1 = 71

significance level = 0.08

t = (3.24 - 3.3) ÷ 0.4/√62 = -0.06 ÷ 005 = -1.2

The test is a one-tailed test. The critical value corresponding to 61 degrees of freedom and 0.08 significance level is 1.654

Conclusion:

Reject the null hypothesis because the test statistic -1.2 is in the rejection region of the critical value 1.654. The claim is contained in the alternative hypothesis, so it is supported.
