In SC 130 Physical Science laboratory ten KG gathered the above data on the index of refraction of water.
Theoretically the index of refraction for water is 1.33. Use a hypothesis test to determine whether KG's data supports a theoretic value of 1.33 (fails to reject the null hypothesis) or disconfirms a theoretic value of 1.33 (rejects the null hypothesis).
Given the following hypothesis:
Null hypothesis: H0: μ = 1.33
Alternate hypothesis: H1: μ ≠ 1.33
Use α = 0.05
n = __________ Calculate the sample size n
x = __________ Calculate the sample mean x.
sx = __________ Calculate the sample standard deviation sx.
SE = __________ Calculate the standard error of the sample mean x.
df = __________ Determine the degrees of freedom.
tc = __________ Calculate the value of tcritical
t = __________ Calculate the t-statistic t.
________________________________________ Would we reject the null hypothesisorfail to reject the null hypothesis at α = 0.05?
__________ Does KG's data supportordisconfirm the theoretic index of refraction of 1.33 water?
