Practice performing the Chi-Squared test with the problems below.
We collected data by flipping a two-sided coin 200 times. The coin landed heads-up 108 times and tails-up 92 times. Perform a Chi-Square test to see if there is any statistical difference between our results and the expected results. Accept or reject the null hypothesis.
Null hypothesis: There is no statistical difference between the number of heads and the number of tails. Outcomes Observed Expected O-E (O-E)2 (O-E)2/E
Outcome Outcome
X Chi Square Value:
Degrees of Freedom:.
Accept or Reject Null Hypothesis:.

Afunction g(x) has x-intercepts at (, 0) and (6, 0). which could be g(x)? g(x) = 2(x + 1)(x + 6) g(x) = (x – 6)(2x – 1) g(x) = 2(x – 2)(x – 6) g(x) = (x + 6)(x + 2)
