Can you help?Show me also how to find the confidence interval for the population variance, and the standard deviation.Thank you!

You randomly select and measure the contents of 10 bottles of cough syrup. The results (in fluid ounces) are shown 4 217 4.294 4 253 4 249 4 183 to the right. 4 218 4 268 4 241 4.227 4 236 Assume the sample is taken from a normally distributed population Construct 90% confidence intervals for (a) the population variance of and (b) the population standard deviation o. Interpret the results A. With 10% confidence, you can say that the population standard deviation is between O B. With 90% confidence, you can say that the population standard deviation is between and inches and |inches O C. With 90% confidence, you can say that the population standard deviation is greater than O D. With 10% confidence, you can say that the population standard deviation is less than inshan
