(e) Interpret the decision in the context of the original claim.Does it appear that peanut candies have weights that vary more than those of plain candies?O A. Since the null hypothesis is rejected, the weights appear to vary more for peanut candies.OC. Since the null hypothesis is not rejected, the weights appear to vary more for peanut candies.O B. Since the null hypothesis is not rejected, the weights do not appear to vary more for peanut candies.O D. Since the null hypothesis is rejected, the weights do not appear to vary more for peanut candies. Use a 0.05 significance level to test the claim that peanut candies have weights that vary more than plain candies. The standard deviation for the weights of plain candies is 0.075. A sample of 71 peanut candies has weights with a standarddeviation of 0.33. Assume the population is normally distributed.(a) Write the claim mathematically and identify Ho and H₂OA. Ho:OB. Ho:OC.

A group of adult males has foot lengths with a mean of 28.43 cm and a standard deviation of 1.13 cm. Use the range rule of thumb for identifying significant values to identify the limits separating values that are significantly 25.7 cm significantly low or significantly high? Explain. Significantly low values are cm or lower. (Type an integer or a decimal. Do not round.) Significantly high values are cm or higher. (Type an integer or a decimal. Do not round.) Select the correct choice below and fill in the answer box(es) to complete your choice. O A. The adult male foot length of 25.7 cm is significantly high because it is greater than cm (Type an integer or a decimal. Do not round.) O B. The adult male foot length of 25.7 cm is not significant because it is between (Type integers or decimals. Do not round.) cm and O C. The adult male foot length of 25.7 cm is significantly low because it is less than cm (Type an integer or a decimal. Do not round.) cm C or significantly high. Is the…
A ski gondola carries skiers to the top of a mountain. Assume that weights of skiers are normally distributed with a mean of 186 lb and a standard deviation of 44lb. The gondola has a stated capacity of 25 passengers, and the gondola is rated for a load limit of 3500lb. Complete parts (a) through (d) below. A. Given that the gondola is rated for a load limit of 3500lb, what is the maximum mean weight of the passengers if the gondola is filled to the stated capacity of 25 passengers? The maximum mean weight is______ B. If the gondola is filled with 25 randomly selected skiers, what is the probability that their mean weight exceeds the value from part (a)? The probability is____ C. If the weight assumptions were revised so that the new capacity became 20 passengers and the gondola is filled with 20 randomly selected skiers, what is the probability that their mean weight exceeds 186 lb, which is the maximum mean weight that does not cause the total load to exceed 3500lb?
