At t = 0 the switch S is closed with the capacitor uncharged.If C = 30 F, = 50 V,and R = 10 k ,what is the potential difference across the capacitor when I = 2.0 mA?
P < .05
A statistical threshold indicating that the probability of observing the obtained result, or more extreme, if the null hypothesis is true, is less than 5%.
T-test
A statistical test used to compare the means of two groups or test a single mean against a known value.
Critical Value
A point on the scale of the test statistic beyond which we reject the null hypothesis; it defines the cutoff between significance and non-significance.
Null Hypothesis
A hypothesis that suggests there is no significant difference between specified populations, or no association among groups.
