Answer:
At the α = 0.10 level, there is no substantial evidence indicating that the average vertical jump for students at this school differs from 15 inches.
Step-by-step explanation:
A hypothesis test is necessary to verify the assertion that the average vertical jump of students diverges from 15 inches.
The null and alternative hypotheses are:
The significance level is set at 0.10.
The sample mean recorded is 17, and the sample standard deviation is 5.37.
The degrees of freedom are calculated as df=(20-1)=19.
The t-statistic is:
The two-tailed P-value corresponding to t=1.67 is P=0.11132.
<pSince this P-value exceeds the significance level, the result is not significant. Therefore, the null hypothesis remains unchallenged.At the α = 0.10 level, there is no compelling evidence that the average vertical jump of students at this school deviates from 15 inches.
Answer:
The universal formula applicable for determining the necessary combinations of n ice cream flavors.
For 10 flavors of ice cream
Step-by-step explanation:
Let's denote V = Vanilla, C = Chocolate, S = Strawberry, P = Pineapple, B = Berry
For 2 flavors of ice cream:
V, C
{V/V, V/C, C/C}
3 possible combinations
For 3 flavors of ice cream:
V, C, S
{V/V, V/C, V/S, C/S, C/C, S/S}
6 possible combinations
For 4 flavors of ice cream:
V, C, S, P
{V/V, V/C, V/S, V/P, C/S, C/P, S/P, C/C, S/S, P/P}
10 possible combinations
For 5 flavors of ice cream:
V, C, S, P, B
{V/V, V/C, V/S, V/P, V/B, C/S, C/P, C/B, S/P, S/B, P/B, C/C, S/S, P/P, B/B }
15 possible combinations
Thus, we derive a sequence of
3, 6, 10, 15...This sequence is recognized as the Triangular number series1 + 2 = 3
1 + 2 + 3 = 61 + 2 + 3 + 4 = 10
1 + 2 + 3 + 4 + 5 = 15The general formula for this sequence isUtilizing this formula allows us to predict the number of 2-scoop combinations from 10 flavors.Consequently, there are 55 varying combinations for a 2-scoop cone when selecting from 10 flavors.
