- For a certain type of salamander, the mass X of a randomly chosen adult is normally distributed. 95% of the adults in this species have a mass between 6.7 grams and 8.1 grams.arrow_forwardA survey of 90 recently delivered women on the rolls of a county welfare department revealed that 27 had a history of intrapartum or postpartum infection. What is the critical value of z if we need to conclude that the population proportion with a history of intrapartum or postpartum infection is less than 0.25.arrow_forwardThe diameter of a metal shaft used in a disk-drive unit is normally distributed with mean 0.2508 in. and std. dev. 0.0005 in. The specification on the shaft have been established as (0.25-0.0015 in, 0.25+0.0015in) If the process mean has been adjusted to 0.25 in, what fraction of the shafts produced does NOT conform to specifications? a). 0.0027 b). 0.0013 c).0.08 d). 0.16arrow_forward
- The sides of a rectangle measure 5 ± 1 (cm) and 8 ± 2 (cm). How much is your area worth?Consider the statistical hypothesis to calculate the propagation of errorsarrow_forwardBeyond 120 df, t and z values are identical. Therefore, some statisticians opt to use z-values when sigma is unknown forarrow_forwardIt is important that face masks used by firefighters be able to withstand high temperatures because firefighters commonly work in temperatures of 200–500°F. In a test of one type of mask, 11 of 55 masks had lenses pop out at 250°(a)Construct a 90% CI for the true proportion of masks of this type whose lenses would pop out at 250°(b)Based on this, what would be your recommendations to the manufacturer regarding this specific face mask?arrow_forward
- The City Council proposed to utilize government-owned land with an area of 9,600 square meters. One-third of the area will be used to plant mango trees while the rest of the land is where an emergency field hospital shall be built. As the city engineer, you were tasked to determine the following: the rate at which the total average number of COVID cases is increasing at x=10 tents and dxdt=1 tent per day, given that if 25 tents are built, the average number of COVID cases per tent will be 6 cases while the average number of cases will increase by 2 per tent for each additional tent in the same area due to overcrowding. Please Include : Illustration and Representation of Variables: Detailed Solution (do not use piecewise): Conclusion:arrow_forwardThe City Council proposed to utilize government-owned land with an area of 9,600 square meters.

- The City Council proposed to utilize government-owned land with an area of 21,600 square meters. One-third of the area will be used to plant mango trees while the rest of the land is where an emergency field hospital shall be built. As the city engineer, you were tasked to determine the following: The rate at which the total average number of COVID cases is increasing at x=10 tents and dxdt=1 tent per day, given that if 30 tents are built, the average number of COVID cases per tent will be 7 cases while the average number of cases will increase by 2 per tent for each additional tent in the same area due to overcrowding. Need: Illustration and Representation of Variables Detailed Solution Conclusionarrow_forwardA sample is counted for 10 minutes and results in 530 gross counts. A 30-minute background count results in 1,500 counts. The detector efficiency is 0.10 cpm/dpm. What is the critical level (net count rate) that corresponds to a risk of making a Type I error, where α is 0.05? a. 3.0 cpm b. 4.2 cpm c. 50 cpm d. 53 cpmarrow_forwardWhat is the critical value?
