Taking the difference of the both you can see that 2 kg of gummy bears would cost $18. So each kg of gummy bear is $9. Now subtract $9 from what Erika bought, and 3 kg of red hots are $12. So each kg of red hots are $4.
Answer:
Step-by-step explanation:
a) This is a right tailed test. The significance level is α. The critical value corresponding to 1 - α is 3.733. From the t distribution table with a df of 15, 1 - α = 0.999
α = 1 - 0.999 = 0.001
b) This is a left tailed test. Degree of freedom, df = n - 1 = 24 - 1 = 23
The critical value corresponding to 1 - α is - 2.500. From the t distribution table with a df of 23, 1 - α = 0.99
α = 1 - 0.99 = 0.01
c) This is a two tailed test. Degree of freedom, df = n - 1 = 31 - 1 = 30
The critical value corresponding to 1 - α/2 is 1.697. From the t distribution table with a df of 30, 1 - α/2 = 0.95
α/2 = 1 - 0.95 = 0.05
α = 2 × 0.05
α = 0.1
The team's point total after 10 games was 10*35 = 350.
The team's point total after 11 games was 11*33 = 363.
The team scored 13 points in game 11.
