Using traditional methods it takes 9.1 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. Set up the hypotheses to test the claim at the 0.05 level that the new technique reduces the training time. State the null and alternative hypotheses for the above scenario.

Using traditional methods it takes 11.4 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. Set up the hypotheses to test the claim at the 0.025 level that the new technique lengthens the training time. State the null and alternative hypotheses for the above scenario.

Using traditional methods it takes 8.7 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. Set up the hypotheses to test the claim at the 0.1 level that the new technique performs differently than the traditional method. State the null and alternative hypotheses for the above scenario.

A scientist has read that the mean birth weight, H, of bables bom at full term is 7.3 pounds. The scientist, belleving that he is different from this value, plans to perform a statistical test. She selects a random sample of birth weights of babies bom at full term and finds the mean of the sample to be 7.6 pounds and the standard deviation to be 1.5 pounds. Based on this information, answer the questions below. What are the nut...

A scientist has read that the mean birth weight of babies bom at full term is 75 pounds. The scientist, believing that the mean birth weight of babies bornet full term is less than this value, plans to perform a statistical test. She selects a random sample of 125 bath weights of babies bom at full term. Suppose that the population of birth weights of babies bom at full term has a standard deviation of 16 pounds and that the...

Using traditional methods, it takes 9.9 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 13 students and observed that they had a mean of 9.8 hours with a standard deviation of 1.5. A level of significance of 0.05 will be used to determine if the technique performs differently than the traditional method. Assume the population distribution is approximately normal. State the null...

Carolina, Inc. has three stores located in three different area. Random samples of the sales of the three stores (in $1000) are shown below. Note that the sample sizes are not equal. We want to conduct an ANOVA test to determine if the means of the three populations are equal. Store 1 Store 2 Store 3 87 75 84 84 78 67 88 60 58 82 62 (1) Compute the overall mean.

Using traditional methods, it takes 10.4 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAN) has been proposed. A researcher used the technique with 9 students and observed that they had a mean of 10.7 hours with a variance of 1.44. A level of significance of 0.1 will be used to determine if the technique performs differently than the traditional method. Assume the population distribution is approximately normal State the null and...

It is known from past information that the average house in America has 2.5 bedrooms. Suppose I take a sample of 28 houses now and find that the average number of bedrooms the homes have is 2.85 with a sample standard deviation of .83. I’m interested in seeing if there is evidence that the average number of bedrooms has increased. Using my sample of 28 houses, what would be the 95% confidence interval for the population mean? What are the...
