A Walton College of Business graduate, wants to start a hot dog stand on Dickson Street. He needs to raise $15,000 for start-up
Artist 52 [7]

Answer:

Yes, he is meeting his original goal to be successful.

The critical value is 1.833

Step-by-step explanation:

H0: mu = 300

Ha: mu > 300

The test is a one-tailed test because the alternate hypothesis is expressed using greater than.

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

sample mean = 335

population mean = 300

sample sd = 50

n = 2×5 = 10

t = (335 - 300) ÷ (50/√10) = 35 ÷ 15.81 = 2.21

Degree of freedom = n-1 = 10-1 = 9

Significance level = 5%

Critical value corresponding to 9 degrees of freedom and 5% significance level is 1.833.

Conclusion:

Reject the null hypothesis because the test statistic 2.21 is greater than the critical value 1.833.

His original goal to be successful is contained in the alternate hypothesis, therefore, he is meeting it.

The length of ladder is 30 ft.

<h3>How can the feet that made up the side of the building is the top of the ladder be known ?</h3>

The formula below can be used in solving the problem

Tan (∅)= \frac{opposite}{adajacent}

∅=70°

opposite = BC

Adjacent  = 12 ft

70°= opposite/ 12

opposite= 32.96 ft

Therefore, The length of ladder is 30 ft.
