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.
Answer:
44/80
Step-by-step explanation:
draw a line from 13cm upwards to the graph line and then draw a horizontal line from that point to the y axis to find that you get 18 bananas
then draw a line from 20cm upwardsto the graph line and then draw a horizontal line from that point to the y axis to find that you get 62 bananas
62-18=44 you do this because the shop buys banana lengths between 13 and 20
only from 13 to 20 = 44
so out of 80 (the total) it should be 44/80
