Two distinct solid fuel propellants, type A and type B, are being considered for a space program activity. Burning rates of the propellant are crucial. Random samples of 26 specimens of the two propellants are taken with sample means 20.1 cm/sec for propellant A and 24.1 cm/sec for propellant B. It is generally assumed that the variability in burning rate is roughly the same for the two propellants and is given by a population standard deviation of 5 cm/sec. Assume that the burning rates for each propellant are approximately normal and hence make use of the Central Limit Theorem. Nothing is known about the two population mean burning rates, and it is hoped that this experiment might shed some light on them. Complete parts (a) and (b) below.

A laboratory's measurement process for chloride concentrations was assessed by randomly inserting 15 specimens having a known concentration 10.0 mg/ l into the normal flow work over a period of two weeks. The work was arranged so that the observed values would be random and independent . The mean and sample variance of these 15 readings is estimated to be 9.46 mg/l and 1.44 (mg/ L)2. The confidence intervals for the true mean is
5. An experiment was conducted to compare the vinegar content of salad dressing on two different production lines. Production was monitored 10 times a day. The data are shown here. For Production line 1, the sample variance si= 2.0, for the production line 2, the sample variance s = 0.4. Find a 98% confidence interval for oi/o. Next ous
A researcher is conducting a stress intervention on high school students and wants to determine if students have improved. The average stress score at baseline is 72with a variance of 14. The average follow up was 82 with variance =16. The teacher calculated the difference between the follow up and baseline for each student and found that 95% conf intervals for mean paired difference was (-0.956, 15.957) n=10 Using the conf interval...calculate average and standard deviation of the paired differences.

Data is collected to compare two different types of batteries. We measure the time to failure of 10 batteries of each type. Battery A: mean= 8.65 Battery B: mean=11.23 Assume equal variances. Perform a .05 level test to determine if Battery B outlasts Battery A by more than 2 hours. Use Sp= .88569 What is the Chart Value for this problem?
Is there a difference in mean daily consumption of coffee between males and females? A random sample of 40 males consumed an average of 2.3 cups per day with a standard deviation of 1.2 cups per day. A random sample of 50 females consumed an average of 3 cups per day with a standard deviation of 2 cups per day. The population variances are not known but assumed to be equal for both males and females. What is the best estimate of the unknown population variance of daily coffee consumption? Round your answer to THREE decimal places.
the homogeneity of variances assumption states that the variance in the two samples must be equal? true
An annual championship event is the most widely watched sporting event in a country each year. In recent years, there has been a great deal of interest in the ads that appear during the game. These ads vary in length with most lasting 30 seconds or 60 seconds. The accompanying data represent the ad length and ad scores from a recent championship. Assuming that the population variances from the 30-second ads and the 60-second ads are equal, is there evidence of a difference in the mean score between the two types of ads? Use α=0.02. Let μ1 be the mean score for the 30-second ads and μ2 be the mean score for the 60-second ads. Determine the hypotheses. Choose the correct answer below. A. H0:μ1=μ2 H1:μ1≠μ2 B. H0:μ1≠μ2 H1:μ1=μ2 C.

The daily number of aluminium rolls produced in a manufacturer of aluminium products is believed to be approximately Normally distributed with a mean 72 and variance 8. As a fresh engineering intern, Alice has recorded the total output for 21 days and found a sample variance of 25. Based on her observations, she wants to infer whether the popuation variance can be considered valid or not. She picks an arbitrary but reasonable confidence level to conclude her analysis. Click here to view page 1 of the table of critical values of the chi-squared distribution. Click here to view page 2 of the table of critical values of the chi-squared distribution. Alice calculates a x value which is equal to. Since it is V (critical value is chosen arbitrarily), she can argue that the population variance valid (Round to three decimal places including any zeros.) greater than x6.01 less than
