qu(16)     The flavour of juicy fruit is said to last on average for 2 mins .A consumer product researcher    wanted to find out  if this is true and hypothesize that juicy fruit flaviour would last longer than average due to changing sticks to pellet pieces. The researcher tested 10  pieces and recorded the following data 1.45  , 1.50 , 1.45,  1.75,  2.15,  2.20 , 1.80, 1.95 , 2.05, 1.60 Test the hypotheses at the 5% level of significance. using the following Step 1: set up NULL hypotheses Step 2: set up Alternative hypothese. Step 3: choose the level signifcance and obtain Zcrt Step 4 :  Calculate  the zobt (using the data and z score)    (sum of(x))**2 =    sum(x**2) =       mean =  Step 5: use Zobt and Zcrt and make a desicion

A researcher reports t(22) = 5.30, p <.01 for an independent-measures research. How many individuals participated in the entire experiment?

please find the test statistic find the p-value for the found test statistic round the p-value to the four decimal places as needed.

You take a survey that is supposed  to measure whether you are an extrovert or not. The score you get on the extrovert survey is a z-score of 2.0. What does that mean about your level of extraversion compared to the average score?

Radon is a gas emitted from the ground that can collect in houses in buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered “acceptable” Radon levels in a house vary from week to week. In one house, a sample of 6 weeks had the following readings for radon level (in pCi/L):    1.9  2.8  3.9  3.9  4.2  5.7 Find the variance and standard deviation (definitional formula). Show your work using a table.

Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 40 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,250 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6,250 lb / 40 = 163 lb. What is the possiblity that the aircraft is overloaded? Should the pilot take any action to correct an overloaded aircraft? Assume that the weights of men are normally distributed with a mean of 177.3 lb and a standard deviation of 39.3 The probability is approximately

A paper investigated the driving behavior of teenagers by observing their vehicles as they left a high school parking lot a then again at a site approximately mile from the school. Assume that it is reasonable to regard the teen drivers in this 2 study as representative of the population of teen drivers. Amount by Which Speed Limit Was Exceeded Female Driver -0.1 0.4 1.1 0.7 1.1 1.2 0.1 0.9 0.5 0.5 (a) Use a .01 level of significance for any hypothesis tests. Data consistent with summary quantities appearing in the pap are given in the table. The measurements represent the difference between the observed vehicle speed and the posted speed limit (in miles per hour) for a sample of male teenage drivers and a sample of female teenage drivers. (Use males #females Round your test statistic to two decimal places. Round your degrees of freedom down to the nearest whole number. Round your p-value to three decimal places.) t= df = P = Male Driver 1.4 1.2 0.9 2.1 0.7 1.3 3 1.3 0.6 2.1

I need you guys help with the attached.

Glaucoma is a leading cause of blindness in the United States, N. Ehlers measured the difference in corneal thickness (in microns) between the two eyes of eight patients. Each patient had one eye that had glaucoma and one eye that was normal. The difference was measured as the corneal thickness of normal eye – corneal thickness of eye with Glaucoma. Corneal thickness is important because it can mask an accurate reading of eye pressure. Use ? = .05. Hypothesis: H0: μd=0Ha: μd≠0 Using output  Test statistics : t=0.134P value=0.897 Degrees of freedom (df): df=7 Level of significance: α=0.05  Decision: P value > 0.05 thus we fails to reject null hypothesis. Question a)Write a report summarizing your findings. When writing the report consider that medical staff estimate that a difference of 4.5 microns or more could impact on their ability to interpret eye pressure correctly. b) Define for the hypothesis stated in part b) what a type 1 error and type 2 error would mean. Is it possible…

Miswrote P(x) 0.041 for 0.141, which changes the mean to 1.5.
