Find the critical value, to for c = 0.99 and n = 10 Let p be the population proportion for the following condition. Find the point estimates for p and q. A study of 4713 adults from country A, 3144 think mainstream media is more interested in making money than in telling the truth. OA. 1.833 The point estimate for p, p, is O B. 2.262 (Round to three decimal places as needed.) DC. 3.169 The point estimate for q, q, is OD. 3.250 (Round to three decimal places as needed.) x 6.2.35-T Question Help Use the standard normal distribution or the t-distribution to construct a 99% confidence interval for the population mean. Justify your decision. If neither distribution can be used, explain why. Interpret the results. In a random sample of 28 families, the average weekly food expense was $95.60 with a standard deviation of $22.50. Determine whether a normal distribution or a In a random sample of 47 people, the mean body mass index (BMI) was 28.5 and the standard deviation was 6.11. t-distribution should be used or whether neither of these can be used to construct a confidence interval. Assume the distribution of weekly food expenses is normally Which distribution should be used to construct the confidence interval? Choose the correct answer below. shaped. A. Use a t-distribution beca se the sample is random, n 2 30, and o is unknown. OB. Use a O A. Use the t-distribution. e sample is random, the population is normal, and a is known C. Use a t-dis O B. Use normal distribution. he population is normal, and o is unknown. D. Use a normal distribution be O C. Cannot use normal distribution or t-distribution. m, n 2 30, and is known. normal. Neither a normal distribution nor a t-distribution can be used because either the sample is not random, or n
