Aproducer of fine chocolates believes that the sales of two varieties of truffles differ significantly during the holiday season. the first variety is milk chocolate while the second is milk chocolate filled with mint. it is reasonable to assume that truffle sales are normally distributed with unknown but equal population variances. two independent samples of 18 observations each are collected for the holiday period. a sample mean of 12 million milk chocolate truffles sold with a sample standard deviation of 2.5 million. a sample mean of 13.5 million truffles filled with mint sold with a sample standard deviation of 2.3 million. use milk chocolate as population 1 and mint chocolate as population 2. which of the following are the appropriate hypotheses to determine if the average sales of the two varieties of truffles differ significantly during the holiday season?

a. h0: µd ≥ 0, ha: µd < 0
b. h0: µd = 0, ha: µd ≠ 0
c. h0: µ1 – µ2 ≥ 0, ha: µ1 – µ2 < 0
d. h0: µ1 – µ2 = 0, ha: µ1 – µ2 ≠ 0

Option d is correct

Step-by-step explanation:

Given that a producer of fine chocolates believes that the sales of two varieties of truffles differ significantly during the holiday season. The first variety is milk chocolate while the second is milk chocolate filled with mint. It is reasonable to assume that truffle sales are normally distributed with unknown but equal population variances.

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
