can i please get help with this ?

We will now compute the Error for a Confidence interval by hand, using: E = za/2 bd Since we're looking for a 95% Confidence Interval, let Za / = 1.96. E = Z«/2 bd bd 30 population proportion of 5's, p, is in the following interval: (p – E,p + E) = This now means that we are 95% Confidence that based on your sample, the true Was the appropriate p in your confidence interval?

Math GW Confidence Interval for a Proportion of 5's Roll your dice a total of n = 30 times. Record x, the number of 5's you roll. Use the number of times you got a 5 to obtain p, the proportion of 5's in your sample. || 30 What do you think p, the population proportion of 5's should be? = d Finally, compute ĝ = 1 – p = 1–
